Sum Drop – Privacy Policy
Last updated 15 September 2026 · Applies to the Sum Drop web game at sumdrop.supertoonz.dev and the Sum Drop app for Android and iOS.
The short version. Sum Drop has no accounts, no ads, no analytics and no tracking. Solo play never leaves your device. The only information the game sends to our server is what you choose to type: a player name for online rooms or the weekly leaderboard, your solo score if you decide to save it, and, if you buy a claimed name on Android, the purchase receipt so we can confirm it with Google Play.
Who we are
Sum Drop is made by Supertoonz. You can reach us at supertoonz.abdul@gmail.com.
What the game stores on your device
The game keeps a few values on your phone or in your browser so it can remember you between plays. They stay on the device and are never uploaded on their own.
- Your best solo score.
- The last player name you typed, so name fields are pre-filled.
- If you claimed a name: the claimed name and the secret key that proves the claim is yours.
Uninstalling the app, or clearing the site's data in your browser, removes all of it.
What is sent to our server, and why
| When | What | Why | Kept for |
|---|---|---|---|
| Playing Battle or Party | The player name you type, the room code, and your taps during the game. | To run the room and show every player the same balloons and scores. | Only while the room exists. When the last player leaves, the room is deleted. |
| Starting a solo game | A request for a signed game token. No personal information. | To stop scores that could not have come from a real game. | Tokens expire after 6 hours. |
| Saving a solo score (optional) | The player name you type, your score, balloons popped and level. | To show this week's top scores to all players. | The board clears itself every Monday 00:00 UTC. |
| Claiming a name (Android, optional purchase) | The name you want, and the Google Play purchase token for your order. | To confirm the purchase with Google Play, reserve the name for you, and give you the key that proves it is yours. | For as long as the claim lasts. A refunded or revoked purchase releases the name and we delete the claim. |
Saving a score is always your choice. The game-over screen offers it and you can decline. Player names are shown to other players in rooms and on the public leaderboard, so please do not use your real full name or anything you would not want others to see.
Purchases
Claimed names are sold through Google Play as a one-time in-app product. Google handles the payment and knows your Google account and payment details; we do not see them. We only receive a purchase token, which we use to verify the order with Google and to check, once a day, whether it was refunded. Google's own privacy policy applies to the payment: policies.google.com/privacy.
Who else sees the data
- Other players see the player names and scores in rooms they are in and on the weekly leaderboard.
- Cloudflare hosts the game and its server. Like any web host, Cloudflare processes connection details such as IP addresses to deliver the service and protect it from abuse. See Cloudflare's privacy policy.
- Google Play processes purchases, as described above.
We do not sell any data, share it with advertisers, or use it for anything other than running the game.
Children
Sum Drop is a maths game that children may play. It does not ask for an age, an email address, a real name or any account. The only free-text field is the player name, which is shown to other players. The claimed-name purchase is made through Google Play and is subject to the parental controls set up on the device.
Security
All traffic between the game and our server is encrypted (HTTPS and secure WebSockets). Claimed-name keys are random secrets that are only ever sent from your device to our server.
Your choices
- Play solo without ever connecting: nothing is sent unless you save a score.
- Decline to save a score, or use any name you like when you do.
- Ask us to remove a leaderboard entry or a claimed name by emailing supertoonz.abdul@gmail.com with the name in question. Refunds for purchases go through Google Play.
- Clear everything stored on your device by uninstalling the app or clearing the site's data.
Changes to this policy
If the game starts collecting anything new, this page will change and the date at the top will move. The current version is always at sumdrop.supertoonz.dev/privacy.
