Privacy policy
Last updated 5 October 2026. This applies to the StampConnections website (stampconnections.net) and the StampConnections mobile app, which are operated by CurioFury LLC.
In short: you can play without an account. We keep a random player id with a screen name and your scores. If you give us an email, we keep it, and your first name, to send the weekly puzzle and to unlock extra levels. We do not sell your information. You can delete everything yourself from Privacy & data.
What we collect
| What | Why | When |
|---|---|---|
| A random player id | To save your scores and games without an account | When you play |
| Screen name, scores | To run the weekly leaderboards and let you continue a game on another device. Your screen name and scores are shown publicly on the leaderboard. | When you choose a screen name or finish a puzzle |
| First name and email address, whether you confirmed it and whether you unsubscribed | To send the weekly puzzle email and unlock extra levels. When you unlock a level we also note which player id is yours, so your email and your screen name can be found together, and deleted together. | Only if you sign up or unlock a level |
| Whether notifications are on | To notify you when a new week is live | Only if you turn notifications on in the app |
| Anonymous usage statistics, such as which puzzles are finished or shared | To understand how the game is used and improve it. No name or email is attached. | App only. The app asks once when you first open it, and nothing is collected until you say yes. You can change your answer any time in Privacy & data |
| 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 site or app |
If you apply to create puzzles, we also keep the name, email and answers you give in that application, and the puzzles you submit.
We do not collect your location, contacts, photos or payment details.
Who handles it
We use service providers to run StampConnections. 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 player record, screen name, scores, saved games and, if you gave one, your email subscription, and removes you from our email list. It does not delete puzzles you made or contributed to.
- By email: write to info@stampconnections.net from the address you used and ask us to delete your data. We will do so 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.
How long we keep it
We keep player and email records until you delete them or ask us to. Analytics data is kept by Firebase for the period set in our Firebase project (up to 14 months).
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
StampConnections is meant for a general audience and is not directed at children under 13. We do not knowingly collect personal information (an email or name) 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 and is stored with Google Firebase. Emailed sign-in links and codes are single-use and expire quickly. 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 and, where appropriate, tell you in the app or by email.
