Welcome to One Line (the "Game"). This policy covers the iOS and Android apps as well as the web and Facebook Instant Games versions. By playing, you agree to what is described here.
01What we collect
So the game runs properly and your progress records correctly, we may collect the following:
| Category | What it is and why |
|---|---|
| Device info | Model, OS version, language setting and an anonymous device identifier — used for compatibility and performance tuning. |
| Game progress | Highest level cleared, levels completed and hints used — used for the ranking board and progress sync. |
| Public account data | If you sign in with a platform account, we receive the public nickname and avatar you authorise, shown only on the ranking board. |
| Usage behaviour | Anonymised statistics such as session length and which levels get retried most — used to tune difficulty. |
| Diagnostics | Crash and error logs used to fix problems and improve stability. These contain nothing that identifies you personally. |
We do not collect your real name, phone number, home address, contacts, precise location or financial details — unless you choose to include them when writing to us.
02How we use it
- Running and maintaining the game, including the ranking board and cross-device progress sync.
- Analysing anonymised statistics to balance level difficulty and improve the hint system.
- Detecting and fixing crashes, stuck boards and impossible results.
- Replying to questions and suggestions you send through the support address or contact form.
- Serving content and handling transactions, if your version includes ads or in-app purchases.
We do not sell your personal data, and we do not pass it to third parties unrelated to running the game for marketing purposes.
03Third-party services
The game integrates the following kinds of third-party services, each of which handles data under its own privacy policy:
- Platform services — Apple App Store, Google Play and Meta (Facebook Instant Games), for sign-in, distribution and platform leaderboards.
- Analytics — anonymised statistics that tell us which levels are too hard or too easy.
- Ads and in-app purchases — where included, these providers may process advertising identifiers and transaction records.
We recommend reading each platform's own privacy policy for the full picture.
04Storage and security
We use reasonable technical and organisational measures to protect your data against unauthorised access, disclosure, alteration or destruction. Data travels over encrypted connections and server-side access is limited to the people who need it.
Progress and ranking records are held in the cloud only for as long as the service needs them. If you ask us to delete them, we remove or anonymise the relevant records within a reasonable period.
05Children's privacy
The game is suitable for a general audience, and we do not knowingly collect unnecessary personal information from children under 13. If you are a parent or guardian and find that your child has provided personal data without consent, contact us using the details below and we will remove it promptly.
06Your rights and choices
- Turn off personalised advertising or reset your advertising identifier in your device settings at any time.
- Ask us to provide, correct or delete the game data associated with you.
- Unlink the game from your platform account at any time, which stops ranking sync.
- Where local law grants further rights (for example the EU GDPR or California's CCPA), we will honour them accordingly.
To exercise any of these, write to support@techbeast.co.
07Policy updates
We may revise this policy from time to time. When we do, the date at the top of this page changes; for significant changes we will also notify you in-game or by another suitable method.
