North Derbyshire Green Party

Appropriate Policy Document

How we handle personal data revealing political opinions, as required by the Data Protection Act 2018.

Version 1.2 · In force from 1 August 2026 · Next review due 1 August 2027

At a glance

Controller
North Derbyshire Green Party, a local party of the Green Party of England and Wales. ICO registration ZB839159.
Party registration
We are an accounting unit within GPEW’s entry on the register of political parties — a constituent organisation responsible for its own financial affairs under section 26 of the Political Parties, Elections and Referendums Act 2000. We are not separately registered as a party in our own right. Section 2 explains what that means for the condition below.
Why this exists
Schedule 1, Part 2, paragraph 5(1) of the Data Protection Act 2018 provides that a condition in that Part is met only if, when the processing is carried out, the controller has an appropriate policy document in place. This is that document.
Condition relied on
Schedule 1, Part 2, paragraph 22 — political parties. Article 9(2)(d) covers our members and regular contacts independently and needs no policy document; paragraph 22 is what takes us beyond them.
Required content
Schedule 1, Part 4, paragraph 39 requires this document to explain our procedures for complying with the Article 5 principles, and our retention and erasure policies with an indication of how long data is likely to be kept. Both are set out below.

1. Scope of this document

This document covers our processing of personal data revealing political opinions — special category data under Article 9 of the UK GDPR. In practice that is unavoidable for a political party: knowing that someone is a member, an activist, a candidate, or attends our meetings reveals something about their political views.

It sits alongside, and does not replace, our Privacy Policy, which describes everything we do with personal data and the rights you have over it. Where the two overlap, the Privacy Policy is the fuller account; this document is the specific record the Data Protection Act requires us to keep.

It covers this website, and it covers the local members and activists list we work from and the contact we make with people on it by email and telephone. That list is held on Action Network, a platform provided to us by GPEW; the platform is GPEW’s, but the decisions we make about who to contact locally and why are ours, and this document covers those decisions.

It also covers the surveys and canvassing we carry out with residents — asking electors at the door or by telephone what they think about their area and how they intend to vote, and recording the answers against their entry on the electoral register. That processing concerns people who are not our members, and it is the largest thing we do that depends on paragraph 22 rather than on Article 9(2)(d). Section 2 explains why, and our Privacy Policy sets out in full what is recorded and what residents can do about it.

It does not cover the Green Party of England and Wales, which maintains the national membership and activist records as a separate controller under its own policies.

Special category data other than political opinions

Paragraph 22 covers political opinions only. One other kind of special category data reaches us without being asked for: GPEW’s platform tags a record when someone joins a Special Interest Group affiliated with the party, and depending on the group that tag can imply something about a person’s ethnicity, religion or belief, disability or health, sex or sexual orientation, or trade union membership.

That data is outside the paragraph 22 condition. We rely on Article 9(2)(d) for it, which requires no policy document, and we apply the handling rules in section 4 to it regardless — we do not copy it into this website’s database, and we do not use it to decide who to contact. We record it here so that the boundary of this document is explicit rather than assumed.

2. The condition we rely on

Processing special category data needs both a lawful basis under Article 6 and a separate condition under Article 9.

  • Article 6 — legitimate interests (Article 6(1)(f)) for running a local party and its website; contract (Article 6(1)(b)) where you have asked us for something specific, such as an account or an event place. The Privacy Policy states the basis for each activity individually.
  • Article 9(2)(d) — processing carried out in the course of the legitimate activities of a not-for-profit body with a political aim, relating solely to its members, former members or people in regular contact with it, and not disclosed outside the party without consent. This is our primary condition, and it covers the great majority of what we do: our members, our activists, our postholders, and people who deal with us regularly. It is directly effective and requires no policy document.
  • DPA 2018 Schedule 1, Part 2, paragraph 22 — processing of personal data revealing political opinions, by an organisation included in the register maintained under section 23 of the Political Parties, Elections and Referendums Act 2000, necessary for the purposes of its political activities. Paragraph 22(4) defines political activities as including campaigning, fund-raising, political surveys and case-work. We rely on this for the processing Article 9(2)(d) cannot reach, because it involves people who are not our members or regular contacts — canvassing and surveying electors, campaigning to the wider public, and case-work for residents who come to us with a problem. Canvassing is by volume the principal example: paragraph 22(4) names political surveys expressly, and a resident who answers the door is neither a member nor in regular contact with us.

Our position on paragraph 22(1)(b)

Paragraph 22(1)(b) requires the processing to be carried out by an organisation included in the register maintained under section 23 of the 2000 Act. That register is a register of parties. Accounting units are not entries in it: they are creatures of section 26, which lets a registered party’s financial scheme identify constituent organisations each responsible for its own financial affairs. We are one of those, within GPEW’s registration.

We consider the condition available to us, because an accounting unit is a constituent part of the registered party rather than a separate party — the political activity is the registered party’s activity, carried on locally. We state the point openly rather than assert bare registration, so that anyone reviewing this document can see exactly what is being relied on.

For most of what we do, this question is not load-bearing. Article 9(2)(d) covers members and regular contacts on its own, and Article 9(2)(e) covers information our councillors and candidates have manifestly made public. Neither depends on the point above.

Canvassing is the exception, and we say so rather than let it pass. Surveying electors who are not members rests on paragraph 22 alone, so if the condition were held to be unavailable to an accounting unit, that processing — together with campaigning contact with non-members and case-work for non-members — would have no Article 9 condition and would have to stop in its present form. Our answer in that event would be to have it carried out under GPEW’s own registration, GPEW being indisputably on the section 23 register, and for us to act on GPEW’s behalf rather than as controller in our own right. We would not simply continue and hope the point was not taken.

The two statutory limits on this condition

Paragraph 22 does not apply without limit, and we treat both exceptions as operative rules rather than background:

  • Paragraph 22(2) — substantial damage or distress. The condition is not met where processing is likely to cause substantial damage or substantial distress to a person. Anyone handling party data who believes a particular use would cross that line must stop and refer it to the contact above before proceeding.
  • Paragraph 22(3) — the right to give notice. If you give us written notice requiring us to stop processing your data, and allow a reasonable period to comply, the condition ceases to apply once that period has ended. This is a statutory right specific to political parties and is in addition to the general right to object under Article 21. Send such a notice to the contact address above; we will confirm receipt and tell you what we have stopped.

3. What we process under this condition

Categories of data processed in reliance on paragraph 22
WhoDataWhy it reveals political opinion
Members and activistsName, email address, roles and team memberships, sign-in records.Holding an account on a party site indicates support for the party.
Committee members and councillorsName, photograph, role or ward, biography, public contact links.Published deliberately — these people represent the party in public.
CandidatesName, photograph, ward, election, biography.Standing for election is a public political act.
People invited to joinEmail address and the roles pre-assigned to them.An invitation implies an existing connection to the party.
Event attendeesName, email address, which occurrence they are attending.Attending a members-only party event indicates affiliation.
Local activists listName, email address, telephone number, area, membership status and organiser tags, held on GPEW's Action Network platform.Being on a party's organising list is the clearest case there is.
People we campaign toName, contact details, and any response given.A recorded response to campaigning may reveal a political view. This is the processing that needs paragraph 22 rather than Article 9(2)(d).
Residents we canvass or surveyElector prefix and number, name, address, views on the local area, voting method, previous vote and expected vote, our canvasser's estimate of their likelihood of supporting a Green candidate, and any email address or telephone number given. Held as our own files, not on this website.A stated voting intention is a political opinion in the plainest sense there is. Paragraph 22(4) names political surveys expressly, and Article 9(2)(d) cannot reach a resident who is neither a member nor in regular contact with us.
Electors generallyElector prefix and number, name and address, from the full electoral register supplied under reg 106 of the Representation of the People (England and Wales) Regulations 2001.The register by itself reveals no political opinion. It is listed because it is the spine every canvass record is attached to, and its statutory restriction to electoral purposes governs everything built on it.
Residents raising case-workName, contact details, and the details of the matter raised.Bringing a problem to a party can reveal an affinity with it. Paragraph 22(4) names case-work as a political activity.

We do not buy personal data and we do not combine our records with commercial datasets. We do, however, use canvass returns to decide which campaign literature is delivered to which address, and that is political targeting — we describe it as such in the Privacy Policy rather than deny it here. Its boundaries are that the support estimate is a canvasser’s manual judgement rather than anything computed, that it determines only which leaflet a household receives, that it is built solely from what the resident told us and the electoral register, and that it is never used for online or social media advertising.

4. Procedures for complying with the Article 5 principles

This section is the explanation required by Schedule 1, Part 4, paragraph 39(a). Each principle is followed by what we actually do, rather than a restatement of the principle.

Lawfulness, fairness and transparency

Art 5(1)(a)
  • Our Privacy Policy states the lawful basis and Article 9 condition for every processing activity, in plain English, and is linked from every page.
  • We tell people what we hold before we ask for it — sign-up is by invitation only, so nobody arrives on our records unexpectedly.
  • We do not sell personal data or share it for anyone else's marketing, and we run no online or social media ad targeting.
  • Where we do something people may not expect — using canvass returns to choose which leaflet reaches an address — we describe it plainly in the Privacy Policy instead of hiding it behind a general denial of profiling.
  • Canvassers identify themselves as Green Party volunteers before asking anything, tell people the questions are optional, and record a refusal as a refusal.
  • Campaigning email and calls go only to people who have consented, as PECR requires. We do not treat the soft opt-in as available to us, because it is not available to political parties.
  • Campaigning email is sent from a party domain that identifies us, carries an unsubscribe link in every message, and is never disguised as something else.
  • Where processing might cause substantial damage or distress, paragraph 22(2) removes the condition and we do not proceed.

Purpose limitation

Art 5(1)(b)
  • Data collected for party administration is used for party administration. Event RSVPs are used to run that event.
  • We do not repurpose the membership or invitation lists for unrelated campaigns, and we send no marketing email from this website.
  • Sharing with the Green Party of England and Wales is limited to the membership and activist relationship and does not extend to website analytics, event attendance by non-members, or sign-in records.
  • Case-work details given to us to get a problem solved are used to solve that problem. Raising something with us does not put a person on a campaigning list.
  • Access to the local activists list is limited to organisers who need it, and it is used for local party organising — not for any other body's purposes.
  • The full electoral register may lawfully be used only for electoral purposes and for complying with donation controls. We treat that statutory limit as the outer boundary of what the register and anything built on it may be used for, and any other use would be a criminal offence as well as a breach of this principle.
  • Contact details given to a canvasser are used to follow up the matter raised, or to send campaigning messages only where the resident specifically agreed and that agreement was recorded. Giving an email address at the door does not put anyone on a mailing list.

Data minimisation

Art 5(1)(c)
  • We ask for an email address to create an account and a name to complete a profile — nothing else is required.
  • Analytics are cookieless and record no individual-level identifier, so audience measurement creates no personal profile.
  • Uploaded photographs are re-encoded on the server, which strips embedded metadata such as GPS coordinates before publication.
  • Joining links for online events are withheld from public pages and sent only to people who need them.
  • We do not collect any other special category data, and delete it if it is volunteered to us without a purpose we have been asked to carry out.
  • Special Interest Group tags visible on GPEW's platform are not copied into this website's database — there is no field for them — and are not used to select who we contact or to tailor what we say.
  • This website never asks for a telephone number. Numbers we hold come from the party's own activists list, or are volunteered by a resident to a canvasser.
  • A canvass asks about local issues and voting intention and stops there. We record no other special category data, and anything of that kind mentioned in passing is removed rather than written down.
  • Canvass returns are held against the elector entry they relate to and are not copied into this website's database, which has no field for any of it.

Accuracy

Art 5(1)(d)
  • Members can correct their own name and profile at any time from the dashboard, without having to ask us.
  • Public profiles are edited by the person they describe, or by an administrator at their request.
  • Changes are audited with before-and-after values, so an incorrect change can be identified and reversed rather than argued about.
  • Rectification requests are actioned within one month.
  • A canvass return is treated as a record of what one person said on one date, not as a settled fact about them. A later canvass supersedes an earlier one, and a resident who tells us the record is wrong has it corrected without argument.

Storage limitation

Art 5(1)(e)
  • Retention windows are declared once in the source code and enforced by an automated daily sweep — see section 5.
  • An invitation nobody takes up expires on its own; an account is not needed for us to stop holding someone's email address.
  • An automated test prevents any retention window being set beyond the 12-month ceiling we publish.
  • Server and container logs are rotated automatically so request records containing IP addresses do not accumulate indefinitely.
  • Records held on GPEW's platform fall under GPEW's retention policy rather than our sweep. We remove people from local organising lists when they leave or ask us to, and we do not keep a local copy that would outlive the platform record.
  • Canvass records are files rather than database rows, so the sweep cannot reach them and we do not pretend otherwise. They are deleted at the end of the electoral cycle they were gathered for, as an identified exception to the 12-month rule — see section 5.
  • Each new electoral register supersedes the previous one, which is destroyed. We keep no historic register copies.

Integrity and confidentiality

Art 5(1)(f)
  • All traffic is encrypted with HTTPS and the database is not reachable from the public internet.
  • We never store passwords. Sign-in uses passkeys or single-use email links; only the public half of a passkey reaches our servers.
  • Access to member records is restricted by role, and administrative areas are separated from ordinary member areas.
  • Sessions and sign-in tokens are short-lived and can be revoked by the member or an administrator.
  • Canvass files and register copies are held in party systems with access limited to the organisers running the campaign they relate to, are never shared outside the party, and paper canvass sheets are destroyed once their contents have been recorded.
  • A personal data breach likely to result in a risk to rights and freedoms is reported to the ICO within 72 hours, and to affected people directly where the risk is high.

Accountability

Art 5(2)
  • This document, the Privacy Policy and our record of processing are kept current and consistent with one another.
  • Retention figures published to the public are generated from the same declaration the software enforces, so the claim and the behaviour cannot diverge.
  • Administrative actions are recorded in an audit log retained for 12 months.
  • One named contact is responsible for data protection and is reachable at the address above.

5. Retention and erasure

This section is the explanation required by Schedule 1, Part 4, paragraph 39(b). Our general rule is that data is kept only while it serves the purpose it was collected for, and that nothing is kept beyond 12 months unless there is a specific reason to keep it longer — an active membership, a published record of who represents residents, or a canvass gathered for an electoral cycle that has not yet ended. Those exceptions are named below rather than left implicit.

Retention is enforced automatically, not left to periodic manual tidying. The windows below are declared in one place in our source code, applied by a sweep that runs every day, and published in our Privacy Policy from the same declaration — so the periods we state and the periods we apply cannot drift apart. An automated test refuses to build the site if any window is set beyond the 12-month ceiling.

Automatically enforced retention windows

Administrative audit log365 daysthe date the change was made

Revoked calendar-feed tokens30 daysthe date of revocation
Expired sessions7 daysthe session's expiry time
Expired OAuth tokens7 daysthe token's expiry time
Spent sign-in links1 daythe link's expiry time (links themselves last five minutes)

Records kept for as long as they remain current

  • Member accounts — while the account exists. Deleted on request, subject to anything we must keep by law.
  • Committee, councillor and candidate profiles — while the person holds the role, plus a reasonable archive period, because there is a public interest in an accurate record of who represented or stood in an area.
  • Correspondence and case-work — up to two years from our last exchange unless it needs to be kept longer as a party record.

Canvass records and the electoral register

These are the one deliberate exception to the 12-month rule, and the only category we keep for years rather than months. A canvass return is gathered to plan a campaign that runs to an election, so a window shorter than the electoral cycle would destroy the data before it had served the purpose it was collected for — and would mean canvassing the same households repeatedly to rebuild what we had thrown away, which is worse for the resident, not better.

  • Canvass returns — kept for one electoral cycle, up to four years and in no event more than five, then deleted. A later canvass of the same area replaces the earlier record rather than being added to it.
  • Copies of the full electoral register — replaced each time a new one is supplied, with the superseded copy destroyed. No historic copies are kept.
  • Contact details given to a canvasser — deleted with the canvass record, or sooner once the matter the resident raised is resolved.

Because these are files rather than rows in the website’s database, the automated sweep cannot reach them: this window is enforced by us, on a review at the end of each cycle. We state that plainly, because a published figure that nothing enforces is worth less than one that a named person is accountable for, and we would rather you knew which kind this is.

Records held on GPEW’s platform

The local members and activists list, the campaigning messages sent from it, and sign-ups for events run on it are held on Action Network, which GPEW provides. Those records are subject to GPEW’s retention policy, not the automated sweep described above, and we say so plainly rather than implying a protection we do not control.

What we do control, and do:

  • people who leave the party or ask to be removed come off the local organising lists;
  • an opt-out from campaigning contact is recorded and kept, because deleting the record outright would let us contact the person again by mistake — the suppression record is the narrowest thing that honours the request;
  • we keep no separate local copy of the list that could outlive the platform record; and
  • a request for erasure that concerns the platform is passed to GPEW and followed up, not simply redirected.

Erasure

Erasure means deletion of the record, not flagging it as inactive. Where a record is deleted, any linked personal data is removed with it or unlinked. Requests for erasure go to the contact above and are actioned within one month. Some material may survive briefly in encrypted backups; those rotate on their own schedule and are not used to reinstate deleted records.

6. Records of processing

Schedule 1, Part 4, paragraph 41 requires our record of processing to note some additional matters for processing carried out under a Schedule 1 condition. Our record states, for each relevant activity:

  • which Article 9 condition is relied on — Article 9(2)(d), Article 9(2)(e), or Schedule 1, Part 2, paragraph 22 — and, where it is paragraph 22, that this document is in place;
  • the Article 6 lawful basis and how the processing satisfies it; and
  • whether the data is retained and erased in line with the policies in section 5 and, if not, the reasons why not.

Changes made through the member dashboard are additionally written to an audit log recording who made the change, when, and the values before and after, so that an incorrect or unauthorised change can be identified and reversed.

7. Retention, review and availability of this document

As required by Schedule 1, Part 4, paragraph 40, we:

  • keep this document in force while the processing continues;
  • review and update it periodically — at least annually, and whenever the way we process data changes materially. The current review date is shown at the top of this page;
  • retain it, and keep it available, until six months after the processing it covers has stopped; and
  • make it available to the Information Commissioner on request, without charge. Publishing it here means it is also available to you.

If you think anything in this document is wrong, or is not being followed, please tell us at louis@hollingworth.nl. You can also complain to the Information Commissioner's Office at ico.org.uk or on 0303 123 1113.
