PRIVACY POLICY

Coil: Retro Snake. Last updated 9 November 2026.

This policy explains what information the Coil iPhone app ("Coil", "the app") handles, why, and the choices you have. The developer of Coil ("we", "us") does not run its own servers for Coil and does not collect, sell or share your personal information. The only data that leaves your device goes to Apple and Google services, as described below.

1. DATA STORED ON YOUR DEVICE

Your settings, scores, game history, coins and unlocked snakes are saved only on your iPhone: in the app's local storage, plus a recovery copy in your device's keychain so your progress comes back if you reinstall Coil. Neither leaves your device and we cannot see them.

2. GAME CENTER (APPLE)

If you are signed in to Game Center, Coil submits your best score for each mode to Apple's Game Center leaderboards and reads your world and daily rank. This is handled by Apple under Apple's Privacy Policy. Your Game Center nickname and scores are visible to other players on the leaderboards. You can sign out of Game Center in the iOS Settings app at any time.

3. IN-APP PURCHASES (APPLE)

Coil offers optional purchases ("Remove Ads" and premium snake sets). Payments are processed entirely by Apple through the App Store. We never receive your payment details. The app only receives confirmation from Apple of what you have bought, so it can unlock it and restore it on a new device.

4. ADVERTISING (GOOGLE ADMOB)

Coil shows a full-screen ad after every few finished games (never during play). Ads are provided by Google AdMob. Players who buy "Remove Ads" see no ads, and the ad SDK then loads nothing.

To show and measure ads, the Google Mobile Ads SDK may collect and process information such as:

• device and app information (device model, operating system version, app version, language, time zone);
• approximate location derived from your IP address;
• advertising identifier (IDFA), only if you allow tracking when iOS asks;
• ad interaction data (ads shown, taps, views) and diagnostics (crash and performance data related to ads).

Google uses this information as described in How Google uses information from sites or apps that use its services and the Google Privacy Policy.

Your choices

• Tracking (App Tracking Transparency). iOS asks whether Coil may track you. If you choose "Ask App Not to Track", your advertising identifier is not shared and ads are not personalised based on tracking. You can change this any time in iOS Settings > Privacy & Security > Tracking.
• Consent in the EEA, UK and Switzerland. If you are in these regions, Coil shows Google's consent form before any ads are requested. You can change your choices later from the Ad privacy choices link at the bottom of Coil's Settings.
• Remove Ads. A one-time purchase turns ads off completely.

5. CHILDREN

Coil is a general-audience game and is not directed at children under 13. We do not knowingly collect personal information from children. Ads are requested without any information that identifies a child.

6. DATA RETENTION AND DELETION

We hold no data about you, so there is nothing for us to delete. You can reset stats in Coil's Settings. The keychain recovery copy stays on your device so a reinstall can restore your progress; erasing the iPhone removes it. Game Center scores are managed by Apple; ad data is managed by Google under the policies linked above.

7. SECURITY

All communication with Apple and Google services uses encrypted connections (HTTPS).

8. CHANGES

If this policy changes, the new version will be posted on this page with a new "last updated" date.

9. CONTACT

Questions or requests about privacy: email support@mindgridstudios.com (see also the support page). If you email us, we receive your email address and message and use them only to reply; you can ask us to delete them.
