chordplay Privacy Policy
Who we are
chordplay ("the app") is provided by xiangying wang. Contact: uprising.river@gmail.com.
What we collect
- Anonymous device ID. The app creates a random ID stored on your device. We use it to count your requests and link your subscription status. It is not linked to your name, email address or advertising identifier (IDFA).
- Content you provide. The songs you look up or request (song names or links) and your request history. We use them to prepare the song and show your history.
- Purchase information. Subscriptions are processed by Apple; we never see your payment details. We use RevenueCat to verify subscription status; RevenueCat receives your anonymous app user ID and purchase history.
- Usage analytics. We use PostHog to record in-app events such as viewing the paywall, starting a trial or subscription, starting a play-along session and how far you get, and the result of song imports. Events are tied only to the anonymous device ID.
- Microphone. The tuner and "wait for me" mode listen through the microphone. Audio is processed on your device only and is never recorded or uploaded.
We do not collect your name, email address, contacts, location or advertising identifier.
What we don't do
No advertising, no tracking across other companies' apps or websites, and no sale of data.
Third-party services
- Apple (payments and subscriptions)
- RevenueCat (subscription status)
- PostHog (anonymous usage analytics)
- Cloudflare (hosting)
Delete my data
In the app, open Settings and tap Clear my data. This deletes your request history and usage events linked to your anonymous device ID from our servers and asks RevenueCat to delete the anonymous profile. You can also email uprising.river@gmail.com from any address and ask us to delete your data; we will delete the data within 30 days. Deleting the app removes the device ID from your phone, after which the remaining server-side records can no longer be linked to you.
Retention
Data is kept while the app is in use and removed on request as described above. Purchase records may be retained by Apple and RevenueCat under their own policies.
Children
The app is not directed to children under 13 and we do not knowingly collect their data.
Changes
We will update this page and its date when this policy changes.
