This site is small and so is this policy. It is written to be read, not to be clicked past.
Who is responsible
sealed.today is operated by Maxime H based in France, acting as the data controller under the GDPR. Contact: hello@sealed.today. Emails about privacy are answered within one month, as the regulation requires.
What is published, permanently
When you claim a pixel you choose a name, a short message, a colour, and optionally a link and a small image. All of it is published on the wall and is visible to anyone. That is the entire point of the site: a day seals at UTC midnight and is not editable afterwards.
Do not put anything in those fields you would not want public forever. Use a first name, a handle, or a company name. There is no need to enter an address, a phone number, or anyone else's personal data — and you must not enter someone else's data without their agreement.
Legal basis: performance of the contract you enter into when you buy a pixel (Art. 6(1)(b) GDPR), and your consent for the specific content you choose to publish (Art. 6(1)(a)).
Payments
Card payments are handled entirely by Stripe. Your card number never reaches this site's servers and is never stored here. What is stored is the Stripe checkout session identifier, so a payment can be matched to the pixel it bought and refunded if the pixel could not be seated.
Stripe acts as an independent controller for the payment data it collects. See the Stripe Privacy Policy. Legal basis: performance of the contract, and Stripe's legal obligations around payment records.
Visitor counting
Each day shows how many people looked at the wall. To count you once rather than ten times, the server takes your IP address and browser user-agent string, mixes them with the current date and a secret salt, and keeps only the resulting SHA-256 hash. The hash cannot be turned back into your IP address, it changes every day, and it is deleted automatically after three days. Only the anonymous total survives on the day's row.
There are no cookies, no local storage of personal data, no analytics scripts, no advertising, no third-party trackers, and no profiling. Legal basis: legitimate interest in a simple, aggregate visitor count (Art. 6(1)(f)).
Server logs
The hosting infrastructure writes technical request logs, which may contain IP addresses, for security and debugging. They are retained for a short period and then deleted automatically. Legal basis: legitimate interest in keeping the service running and secure.
Where the data lives
Everything is hosted in the European Union: application and content delivery on Amazon Web Services (Paris region), the database on Supabase (Paris region). Stripe processes payments and may transfer data outside the EU under the European Commission's standard contractual clauses. There are no other processors.
How long it is kept
- Published claims: indefinitely. Permanence is the product.
- Stripe session identifiers: as long as the claim they belong to.
- Visitor hashes: up to three days, then deleted by an automated job.
- Server logs: a short retention window, then deleted automatically.
Your rights
You may request access to your data, correction, erasure, restriction, portability, or object to processing based on legitimate interest. Write to hello@sealed.today.
On the permanence of the wall, to be straight with you: the technical design does not allow a sealed day to be re-opened, and the visual record of a claim — its position and its colour — is intended to be permanent. Your right to erasure is not waived by that. On a valid request the operator will redact the personal data in a claim, removing the name, message, link and image, leaving only an anonymous coloured pixel. Ask and it will be done.
If you are not satisfied with the response you may lodge a complaint with the French supervisory authority, the CNIL, or with the authority in your own country.
Children
The site is not intended for children. Do not buy a pixel if you are under 18.
Changes
If this policy changes, the date at the top changes with it. Material changes will be noted on the wall itself.
