Privacy Policy — Cubewit
Effective date: November 14, 2026 · Provider: Bradley (MadeByBang) · Contact: hello@madebybang.com
Cubewit teaches how to solve the 3×3 cube. It is built to collect as little as possible.
Summary
- No accounts, no sign-in, no ads, no third-party analytics or tracking.
- Learning progress stays on your device; the app does not sync it to our server.
- Camera images are processed on the device and discarded: never stored, never sent.
- Users under 15 (the 6–9 and 10–14 groups in the app) send no data to any server.
- Only users in the 15+ group who agree send a little data about a solve to receive tips written by AI.
On the device
The app stores:
- the chosen age group, skill and language;
- exercise results: which exercise, turns, hints used, time;
- minutes of use per day, for the parent's daily limit;
- a random install code.
The app never sends this to our server, except as described under AI tips. Uninstalling removes it from the device. Because it lives in the app's storage, device backups (iCloud or a computer, depending on your backup settings) may contain it. Uninstalling does not delete existing backups, and restoring a device from a backup may restore your progress.
Camera
The camera is used only to read the nine sticker colours of each face. Images are analysed on the device and never stored or sent. You can refuse camera access and enter colours by hand.
AI tips (15+ only, with consent)
Data sent
After a solve, when you are in the 15+ group and have opted into "Online AI tips", the app sends our server:
- the solve steps (turns, stages, cases), skipped stages and weakest stage;
- skill, language, and the kind of text needed;
- the random install code, in a separate header, only to limit how often each install can call.
It sends no images, names, email, phone number or operating-system device identifiers. Like any internet connection, the server sees your IP address.
Who processes it and for how long
| Where | Data | Kept for |
|---|---|---|
| Our server (Cloudflare Workers) | Install code and IP address, only to count calls | Rate-limit counters live for a 60-second window. The server stores the install code and IP nowhere else, and its request logs are off |
| Tip cache (Cloudflare KV) | Written tips, keyed by solve features (language, skill, stages, cases). The key holds no install code, IP or moves | Deleted automatically after 30 days |
| Totals (Cloudflare Analytics Engine) | Counts only: which kind of call (new, cached, prepacked). No install code, IP or content | Per Cloudflare's retention for Analytics Engine |
| AI gateway (Cloudflare AI Gateway) | Request and response content is not logged (payload logging off). Gateway logging is fully off | Not retained (0 days) |
| DeepSeek (AI service, servers in China) | The solve content above, without your install code or IP | Per DeepSeek's API data policy: DeepSeek Privacy Policy |
Turning off and deletion
- You can turn "Online AI tips" off at any time in Settings; the app then uses prepacked tips and sends nothing.
- We keep nothing linked to you or your install code beyond the 60-second window above, so there is no record to delete on request.
- Questions: contact

Children
For the 6–9 and 10–14 groups the app makes no server calls and sends nothing off the device. The parent area (progress, daily limit, profile changes) and links out of the app are behind a question meant for adults.
Changes
We update this page and its effective date when this policy changes.
