Privacy Policy
Last updated: 26 June 2026
This policy explains how Pocket Sounds ("we", "us") handles information in our apps, including Guitarium. We keep it short because we collect very little.
The short version
- No account, no sign-up. You don't give us your name or email to use the app.
- We don't sell your data, and we don't show ads.
- We collect anonymous usage analytics to understand which features help people practice.
- Your practice progress is stored on your device and in your own iCloud — we can't read it.
What we collect
Anonymous usage analytics. We use Google Analytics for Firebase to see how the app is used in aggregate — which drills are practiced, how long sessions last, which tools (tuner, metronome, scales, songs) get used. This includes:
- Usage data — in-app events and interactions (e.g. a drill started, a feature opened), with no personal content.
- A device identifier — a random app-instance ID used to count distinct devices. It is not your name and is not tied to your identity.
- Approximate location — a coarse region (e.g. country/city) inferred from your IP address by the analytics provider. We do not collect precise GPS location.
This data is pseudonymous and is not used to track you across other apps or websites. We do not use the Advertising Identifier (IDFA).
What stays on your device
- Microphone (tuner). The tuner listens through your microphone to detect pitch. Audio is processed live on your device and is never recorded, stored, or sent anywhere.
- Practice progress. Your sessions, XP, streaks, and stats are stored on your device and synced through your private iCloud account (Apple CloudKit) so they follow you across your devices. This uses your Apple ID — we have no access to your iCloud data.
- Settings & preferences are stored locally on your device.
Purchases
Subscriptions are handled entirely by Apple through the App Store. We never see or store your payment details. Your subscription status is verified on-device via Apple's StoreKit.
Third parties
The only third party that receives data is Google (Firebase Analytics), which processes the anonymous usage data described above. See Firebase's privacy and security information and Google's Privacy Policy. Apple processes purchases and (optionally) iCloud sync under Apple's Privacy Policy.
Your choices
- You can reset or disable the analytics identifier in your device's settings, or stop all collection by deleting the app.
- You can turn off iCloud sync for the app in Settings → [your name] → iCloud.
Data retention
Aggregated, anonymous analytics are retained by our analytics provider for a limited period and then deleted automatically. On-device and iCloud data persist until you delete the app or clear it from iCloud.
Children
Guitarium is not directed at children under 13, and we do not knowingly collect personal information from children.
Changes
We may update this policy as the app evolves. Material changes will be reflected by the "last updated" date above.
