Privacy policy
Last updated 5 October 2026. This applies to the StampMind website (stampmind.net) and the StampMind mobile app, which are operated by CurioFury LLC.
In short: you can play without an account. We keep a random player id with your games and, if you choose one, a leaderboard screen name. If you give us an email, we keep it, and your first name, to send the weekly StampMind update. We do not sell your information. You can delete everything yourself from Privacy & data.
What we collect
| What | Why | When |
|---|---|---|
| A random player id, made by your browser and kept in it | To keep your games, statistics and streak without an account | When you play |
| Your moves and results for each daily stamp | To run the game fairly (the answer is checked on our server), to show your statistics, and to work out how everyone did | When you play |
| Screen name | To show you on the daily leaderboard. Your screen name, score and the kinds of move you made are shown publicly there; the player id never is. | Only if you choose a screen name |
| First name and email address, and whether you unsubscribed | To send the weekly StampMind update. The browser you signed up in remembers a token for your subscription, so your email and your player record can be seen, and deleted, together. | Only if you sign up for weekly updates |
| Standard server logs (such as IP address and time) kept by our hosting provider | To keep the service running and secure | Whenever you use the game |
We do not collect your location, contacts, photos or payment details, and StampMind does not use analytics or advertising trackers.
Sponsors
The sponsor banner under the game shows every player the same sponsors in turn; nothing about you is used to choose them. We count how many times each sponsor is shown and clicked per day. Those counts hold no player id, address or device. If you click a sponsor you go to their website, which has its own privacy policy.
Who handles it
We use service providers to run StampMind. They process information for us and may not use it for their own purposes.
We do not sell your information, share it for advertising, or track you across other apps and websites.
Deleting your data
You can delete everything we hold about you yourself:
- In the app or on the website: open Privacy & data (at the bottom of the page) and choose Delete my data. This permanently deletes your games, statistics, streak and screen name, removes you from every leaderboard, deletes your email subscription if you signed up in this browser, and makes your browser forget its player id.
- By email: write to info@stampconnections.net. Write from the address you signed up with, or tell us your screen name, so we can find your record. We will delete it within 30 days.
- Just the emails: every email has an unsubscribe link.
Deleting is permanent. Backups and logs held by our providers are removed on their normal schedules. Clearing your browser's site data also makes it forget its player id, but leaves the record on our server; use Delete my data first if you want that gone too.
How long we keep it
We keep player and email records until you delete them or ask us to.
Your rights
Depending on where you live (for example under the GDPR or California law) you may have the right to access, correct, delete or export your information, and to object to some uses. Write to info@stampconnections.net and we will help. You can also complain to your local data protection authority.
Children
StampMind is meant for a general audience and is not directed at children under 13. We do not knowingly collect personal information from children under 13. If you believe a child has given us any, write to us and we will delete it.
Security
Data travels over encrypted connections. The player id in your browser is what identifies you to the game, so anyone with access to your browser can see your games. No system is perfectly secure, but we take reasonable steps to protect your information.
Changes
If we change this policy in a way that matters, we will update the date above.
