IDK Play

Privacy policy

Last updated: October 12, 2026

IDK Play is a practice planner for musicians. The short version: the developer does not collect any of the information you put into it.

What the app does not do

Information you enter

Your library (song titles, optional links, lengths, tags, and notes), your saved practice sessions, your Generate settings, and your preferences (such as whether Setlist lettering is on) are stored on your iPhone, inside IDK Play’s own storage. The developer has no access to them.

When you add a song through the Share sheet (“Add to IDK Play”), the song waits in a small file shared only between IDK Play and its Share extension on your iPhone, and moves into your library the next time you open the app.

Like other app data, this information can be included in your iPhone’s backups, which you control through Apple.

iCloud (only if it is turned on in a future version)

IDK Play currently keeps your data on your iPhone only. If a later version offers iCloud sync, your library and sessions would be stored in your own private iCloud database, which belongs to your Apple Account. The developer cannot read private iCloud databases. Apple’s privacy policy covers iCloud. This policy will be updated before any such change ships.

Network connections

IDK Play contacts the internet in only two situations, both started by you:

  1. Reading a YouTube video’s length. When you share a YouTube link to IDK Play, the Share extension requests that video’s public YouTube page directly from your iPhone and reads the video’s length from it, so you don’t have to type it. The request goes straight to YouTube, not to the developer, and includes only what any web request includes (such as the video address and your device’s IP address). YouTube’s handling of that request is covered by Google’s privacy policy. Nothing else from your library is sent.
  2. Opening a link. When you tap a song’s link, it opens in Safari or the app that handles it (for example YouTube). What happens there is covered by that website’s or app’s own policy.

Deleting your data

Because the developer holds no copy of your data, there is nothing further to request or delete.

Children

IDK Play is suitable for all ages and does not knowingly collect information from anyone, including children.

Changes

If this policy changes, the new version will be posted at this address with a new “Last updated” date. Material changes, such as turning on iCloud sync, will also be mentioned in the app’s release notes.
