FAQ.

Stamp is a small, paid social app for the people you already know. One post a day, only your invited circle sees it. No ads, no algorithm, no strangers, no public feed. It's a gentler way to share, designed so you put your phone down once you've seen what your circle is up to.

£3 per month, or £30 a year (save £6). Everyone pays the same price. No tiers, no premium add-ons, no upsells, no in-app purchases. The flat fee is how we pay the bills without selling your attention to advertisers.

Yes. Every new member gets 30 days free. No card required upfront for the trial.

Stamp launches on the iOS App Store and Google Play in August 2026. Until then this website is the public-facing version; if you'd like an invite to the London launch event in late September, write to hello@stamp.foundation.

Stamp launches in the United Kingdom first. We'll open up to other countries over time, starting with English-speaking markets. Wherever Stamp is available, the £3 / £30 pricing, the Terms, and the Privacy Policy stay the same. The charity pool stays UK-registered no matter where members are based.

You pay £3 a month to Stamp Social Ltd, the UK company that operates the app. From whatever profit the company has left at the end of each quarter, after paying every cost (salaries, hosting, professional fees, repaying money the founder lent to start the company, and tax), we split what remains in half. Half is donated to UK-registered charities; the other half is reinvested in Stamp (the team, growth, and reserves). The donation is made by the company, not by you. You are buying a subscription, not making a donation.

If the company makes no profit in a quarter, no donation is made for that quarter and no shortfall accrues against a later quarter. That is the only honest way to describe how charity funding works on Stamp.

Three UK-registered charities at a time, equal split, paid on the last working day of March, June, September and December. For Year 1 (October 2026 to December 2027) the founder picks the three directly, with the reasons published alongside each name before launch. From the December 2027 vote onward, charities self-submit and Stamp members vote in the first week of December each year. The three winning charities receive payments throughout the following calendar year. Every transfer is published on the public ledger within three working days.

Three is deliberate. Splitting the pool three ways instead of ten means each charity receives a materially larger share, which matters more than breadth at our scale. Three also makes the annual member vote legible: you know what the choices were and what you chose.

Stamp is not a charity. Stamp is a UK limited company (Stamp Social Ltd, Company No. 17188757) that operates a paid app. The trading name "Stamp Foundation" is a brand, not a separate legal entity, and Stamp Foundation is not itself a registered charity. The three charities the company donates to are UK-registered charities, regulated by the Charity Commission (or by OSCR in Scotland, or CCNI in Northern Ireland). The money flows directly from Stamp Social Ltd to each registered charity, not via the Stamp Foundation brand.

No. Your £3 / £30 is a subscription payment for a product, not a charitable donation. We can't issue a Gift Aid declaration, and HMRC wouldn't accept one for a subscription fee. The donation to charity is made by Stamp Social Ltd from the company's post-cost profit, so any charitable-giving tax treatment sits with the company, not with you.

Only the people in your circle. Every connection is mutual: you request, they accept, then your posts are visible to them and theirs are visible to you. There's no public profile, no follower mechanic, no explore feed, no way for a stranger to find you. You can also choose to publish a post to a smaller inner circle inside your wider circle.

One-to-one text messages are end-to-end encrypted with industry-standard encryption: sealed on your device, addressed to specific devices in the conversation, and unreadable on our servers. Voice and video calls use end-to-end encrypted media (DTLS-SRTP) with keys negotiated directly between the devices on the call.

Group chats, voice notes and photo attachments are not yet end-to-end encrypted. They use TLS in transit and AES-256 at rest on our database. Extending end-to-end encryption to group chats and attachments is on the roadmap for our next native build. Posts, events and profile fields are intentionally not end-to-end encrypted, because they are meant to be visible to your circle.

Account information (name, @handle, email, hashed password, birthday if you choose to add one), the content you post, your circle relationships, and basic device information needed to deliver the app. Precise location is only collected when you turn "Show location on posts" on, and only on posts where you actively add a place. No advertising identifiers, no third-party trackers, no contact-list upload. The microphone is only used when you tap record or accept a call; the camera only when you pick or take a photo or join a video call.

Delete: open the Stamp app, go to Profile → Settings → Delete account. Your posts, profile, circle records, messages, voice notes and album are wiped from our live systems immediately. Our automatic database backups roll off within 7 days, after which everything is gone from there too. There is no "deactivated" purgatory and no shadow profile.

Data export: in the app, Profile → Settings → Email me my data. We pack your posts, captions, album saves, profile fields and message metadata into a single structured JSON file, with signed download links for your photos, and email you the link. The link is valid for 7 days. If you'd rather we did it for you, or you'd like to make any other UK GDPR request (access, correction, restriction), email privacy@stamp.foundation and we'll respond within one month.

No. We do not sell your data. We do not share it with advertisers. We do not license it. We use a small number of operational sub-processors (hosting, payments, error reporting, image-safety scanning) under data-processing agreements so they handle it only on our behalf. The full list, and the role each one plays, is in our Privacy Policy.

Each daily post can include up to three photos and a caption. Inside chat you can send voice notes, photos and short calendar-availability snapshots to people in your circle. You can pin a 30-second song preview to your profile or to an individual post; if you're a musician, you can link your own track from a streaming platform. Beam, a separate chat feature, sends full-quality uncompressed photos (up to 3 Beams a day, 30 MB per file) and keeps them in the chat alongside your other messages, marked with a small blue ring.

Your circle is the set of people you've mutually connected with on Stamp. Everyone in your circle can see your daily post by default, and you can see theirs. Inner circles are smaller groupings you create inside your circle, for family, school friends, work, and so on. When you post you can choose to publish to your full circle or to a specific inner circle. You can also flip your own profile to a "view as your circle" mode to check what your circle actually sees, before you post anything.

Reports go to a human reviewer, not an algorithm. For clearly illegal material (CSAM, threats, non-consensual intimate imagery, terror content) we act within 24 hours and report to the relevant authorities. For policy-breach material that isn't unlawful, we acknowledge within 48 hours and decide within 7 days. If your content or account is actioned, you get a written reason and a working appeal route to a different reviewer.

If you need to talk to someone urgently about your own safety, Samaritans can be reached free in the UK on 116 123, any time.

No. Your feed is chronological and that is a deliberate commitment, not a default you can switch. There is no "for you" tab, no recommendation, no engagement-ranking, no boosted posts. When you've seen the day's posts from your circle, you've seen them.

Stamp is built for phones. iOS and Android are the supported platforms; the website you're reading is informational only and doesn't include a working version of the app. We aren't planning a desktop client at launch. A read-only or messaging-only web companion may come later, but it's not promised and not on the near-term roadmap.

If you subscribed on iPhone: open the iOS Settings app, tap your name at the top, then Subscriptions → Stamp → Cancel. On Android: open the Play Store, tap your profile picture, then Payments & subscriptions → Subscriptions → Stamp → Cancel. Cancellations always take effect at the end of the period you've already paid for.

You keep full access until the end of the period you've already paid for. After that the subscription stops and you can't post or message until you renew. Your account is not deleted automatically: if you renew later, your circle and your posts come back as they were. If you want everything erased, use Profile → Settings → Delete account inside the app.

Refunds for subscriptions purchased on iPhone or Android are handled by Apple and Google respectively, under their own refund policies. Apple: reportaproblem.apple.com. Google Play: play.google.com/store/account → Order history. Your statutory rights under the UK Consumer Rights Act 2015 apply either way.

For most things, hello@stamp.foundation. We aim to reply within 48 hours on weekdays. For privacy or data questions, privacy@stamp.foundation. To report a post, message or account, safety@stamp.foundation (or long-press in the app). To appeal a moderation decision, appeals@stamp.foundation.

Stamp is built solo so far, by the founder, and operated by Stamp Social Ltd. The team page introduces who is working on it today. We are hiring as Stamp scales.

Stamp is funded by subscription revenue only. No advertising, no data sales, no sponsored content. At launch we are not raising outside investment, the founder has put in personal money to build the app, recorded as a director's loan that the company will repay out of revenue. If we ever raise from investors in future, we will say so on this page and on the company filings at Companies House.

The company is registered in England and Wales. Stamp Social Ltd, Company No. 17188757, registered office 71-75 Shelton Street, Covent Garden, London WC2H 9JQ. The company is registered with the UK Information Commissioner's Office under the Data Protection Act 2018, registration number ZC142084.

Reasonable question, and the answer is that you don't have to take our word for it. You can check three observable things. One: the company is on the public Companies House register (No. 17188757) with the registered office and directors filed. Two: the company is on the public ICO register (ZC142084) as a data controller. Three: every charity transfer we make will be posted on our public ledger within three working days, so you can see the receipts on a timetable. If a payment doesn't appear when it should, anyone, including journalists and regulators, can ask why.

None of this is a guarantee. It's just observable enough that we can't quietly walk away from what we've published.
