Privacy Policy
Unknot: Arrow Art Puzzle · Last updated 22 October 2026
Unknot is a puzzle game. We want you to enjoy it without giving up your privacy. This policy explains what the game collects, why, and the choices you have.
What we collect
We do not ask for your name, email address, phone number, contacts, photos or precise location, and you do not need an account to play.
| Data | Why |
|---|---|
| A random install identifier created by the app on first launch, and Apple's identifier for vendor (IDFV) | To tell one installation's gameplay apart from another's, so we can measure retention and fix problems. It is not linked to your identity. |
| Gameplay events: levels started and finished, taps, mistakes, hints, session start and end times, settings changes | To balance difficulty, find bugs and decide what to improve. |
| Device information: device model, iOS version, language, time zone, screen size, app version, and the country derived from your IP address (the IP address itself is not stored) | Compatibility, performance and regional statistics. |
| Purchase records: product, price, currency and the App Store transaction identifier | To deliver what you bought and to account for revenue. Payment is handled entirely by Apple; we never see card details. |
| Ad events: which ad format was shown, where in the game, and the revenue the ad network reported | To control how often ads appear and to measure what keeps the game free. |
The app stores events on your device and uploads them when you are online, so short offline sessions are counted too.
Advertising and tracking
The free version shows ads from third-party ad networks (for example AppLovin and its mediated partners). These partners may collect device and usage data to show and measure ads under their own privacy policies. If the app asks for permission to track (Apple's App Tracking Transparency prompt) and you decline, the advertising identifier (IDFA) is not shared and ads are not personalised. You can change this at any time in iOS Settings → Privacy & Security → Tracking.
We use Apple's SKAdNetwork and Meta's aggregated measurement to learn which ad campaigns brought new players, without identifying you.
How long we keep data
Gameplay and device events are kept for up to 24 months and then deleted or aggregated so they no longer relate to an installation. Purchase records are kept as long as accounting law requires.
Sharing
We do not sell personal data. We share data only with service providers that run the game for us (cloud hosting by Cloudflare, ad mediation and ad networks, and Apple), and only as needed for the purposes above, or when the law requires it.
Your choices and rights
- Delete your data: open Settings in the game and tap "Delete my data", or email us your install ID (shown on that screen). We delete everything linked to it.
- Stop data collection: deleting the app stops all collection.
- Depending on where you live (for example under the GDPR or CCPA), you can also ask for access to, correction of, or a copy of your data, and complain to your data protection authority.
Children
Unknot is not directed at children under 13 (or the minimum age in your country), and we do not knowingly collect data from them. If you believe a child has used the app, contact us and we will delete the data.
Changes
If we change this policy we will update the date above, and for significant changes we will tell you in the app.
