Privacy Policy

Last updated: October 6, 2026

The short version

1. Who we are

ClaimASlot (claimaslot.com) is a small independent project based in the Netherlands ("we", "us"). We are the data controller for the personal data described in this policy. You can reach us at hello@claimaslot.com or through our contact page.

2. What data we process

When you create a sheet (organizers)

The sheet's title, description, location, the optional organizer name you enter, the slots (names, dates, times, number of spots and notes) and whether names are shown publicly. We also record when the sheet was created and changed. We generate a secret organizer link for you; we store only a one-way cryptographic fingerprint (SHA-256 hash) of it, never the link itself.

When you sign up (participants)

The name you enter, an optional note, which slot you chose and when you signed up. We generate a private link that lets you change your sign-up; again, we store only a fingerprint of it.

Technical data

Like every website, our servers receive your IP address and basic browser information when you visit. Our hosting provider, Cloudflare, processes this to deliver pages and protect the site against attacks. To prevent spam and abuse, when you create or change something we count requests per network per hour. We never store your IP address itself: only a pseudonymized hash of your network, made with a secret value that changes every day and is then deleted, so old counters can't be linked back to you. Counters are normally deleted after about two hours.

Website statistics

We don't use analytics scripts or trackers on our pages. We only look at the aggregated traffic totals our hosting provider reports (such as the number of requests per day), which don't identify individual visitors.

Abuse reports and messages

If you report a sheet or email us, we process what you send us, including any contact details you choose to give.

Data stored only on your device

To let you manage your sheets and sign-ups without an account, your browser's local storage keeps your organizer links, your sign-up links and the name you last used. This information stays on your device and is not sent to us except when you use it (for example to edit your sheet). See our Cookie Policy.

What we don't collect

We don't ask for email addresses, phone numbers, payment details, precise location or any sensitive data. Please don't enter sensitive information (such as health details, financial information or ID numbers) into a sheet.

3. Why we use it and our legal basis

We don't use your data for automated decision-making or profiling, and we don't use it to train AI models.

4. A note for organizers

When you organize a sheet, you decide what to ask for and who you share it with. Please collect only what your event needs, tell participants what the sheet is for, and don't add other people's personal data without their permission. For school or children's activities, first names are enough. If you use ClaimASlot on behalf of an organization, that organization may have its own responsibilities under data protection law for the names it collects.

5. Who can see your data

We don't sell personal information, don't share it for cross-context behavioral advertising and don't give it to data brokers.

6. International transfers

The database that stores sheets and sign-ups is located in the European Union. Cloudflare operates a global network to deliver the website quickly, so requests may pass through servers in countries outside the European Economic Area, including the United States. Cloudflare is certified under the EU-U.S. Data Privacy Framework (and its UK and Swiss extensions), and transfers are also covered by the European Commission's Standard Contractual Clauses.

7. How long we keep data

DataKept for
Sheets and all sign-ups on themUntil 30 days after the last date on the sheet, or 180 days after the last change if it has no dates (at most two years). Then deleted automatically. Organizers can delete a sheet at any time, and participants can remove their own sign-up.
Pseudonymized network hashes and request countsNormally about 2 hours; the daily secret used to make them is deleted after a day
Abuse reports180 days, or longer if needed for a legal claim or obligation
Emails you send usAs long as needed to handle your question, at most 2 years
Data in your browser's local storageUntil you clear it; you control this

Deleted data may remain in Cloudflare's backup systems for a short period before it is overwritten.

8. How we protect your data

No system is perfectly secure. If a breach affects your personal data, we will notify the authorities and, where required, you.

9. Your rights

Depending on where you live, you have the right to:

The fastest way: remove your sign-up yourself on the sheet, or as an organizer delete the sheet. Otherwise email hello@claimaslot.com with the sheet link and the name you used. Because we don't have accounts, we may ask for details to confirm that a request is genuinely yours. We respond within one month. Exercising your rights is free.

In the EU you can complain to your local data protection authority. Our lead authority is the Autoriteit Persoonsgegevens (Dutch Data Protection Authority), autoriteitpersoonsgegevens.nl.

10. Additional information for US residents

This section applies to residents of California and other US states with consumer privacy laws (such as Colorado, Connecticut, Virginia, Utah, Texas and Oregon).

11. Other regions

If you are in the United Kingdom, you have the rights described in section 9 under the UK GDPR and can complain to the Information Commissioner's Office (ico.org.uk). Residents of Canada (PIPEDA), Brazil (LGPD), Switzerland (FADP), Australia and other countries have similar rights; contact us to use them.

12. Children

ClaimASlot is a general-audience service and is not directed at children under 13. In the EEA, people under 16 should only use it with permission from a parent or guardian. Parents and teachers may add a child's first name to a sheet for school activities; please don't add more information than needed. If you believe a child has given us personal data without permission, contact us and we will delete it.

13. Changes to this policy

We will update this policy if our practices change, for example when we switch on advertising. For significant changes we will show a notice on the site, and where the law requires your consent (such as for advertising cookies), we will ask for it first. The date at the top shows the latest version.
