Privacy Policy for Songbook

Last updated: August 17, 2026

This Privacy Policy describes how Songbook ("the app", "we", "us") handles your information. Songbook is developed by John Harold Rasco.

We designed Songbook to collect as little as possible. There is no sign-up and no personal account. The only way to give us any contact information is to type an email address into the feedback form yourself, which is entirely optional.

Information we collect

Information stored only on your device

Selected karaoke machine. Your machine choice is saved in your device's local settings so the app remembers it between launches.
Favorited songs. When you favorite a song, the favorite is stored in a local database on your device.

This information never leaves your device unless described below.

Information sent to our servers (Google Firebase)

When you favorite a song, the app sends the following to our backend so we can power the community Top 100 list:

An anonymous user ID generated by Firebase Authentication. This ID is not linked to your name, email, Apple ID, or any personal information.
The song's title, artist, song number, volume, and the karaoke machine model.
A timestamp.

Feedback you choose to send

The app has a "Send Feedback" option under the More tab. Nothing here is collected unless you write a message and tap Send. When you do, we receive:

Your message. Whatever you type, in full. Please don't include anything sensitive — write it as if you were emailing us, because that's effectively what happens.
The feedback type you selected (a problem, a feature request, or something else).
Your reply email address — only if you choose to enter one. The field is optional and may be left blank; submitting works either way. We use it solely to reply to you, and for nothing else.
Basic technical context so we can act on the report: your app version and build, your device model (e.g. "iPhone16,2" — a hardware model shared by millions of units, not a unique identifier), your iOS version, your device language, the karaoke machine you have selected, and the same anonymous Firebase user ID described above.

The app shows you this list on the feedback screen before you send. Submitted feedback is emailed to the developer so it can be read and acted on.

We do not collect:

Your name, phone number, or any contact information other than an email address you type into the feedback form yourself
Your precise or approximate location
Photos, contacts, microphone, or camera data
Advertising identifiers (IDFA)
Any data used for tracking across apps or websites

How we use the information

The information we collect is used solely to:

Provide app functionality (saving your favorites and remembering your machine)
Aggregate anonymous favorite counts for the community Top 100 list
Read, understand, and act on feedback you send us, and reply to you if you gave us an address

We do not sell, rent, or share your information with third parties for marketing purposes. We do not use the information for advertising.

Third-party services

Songbook uses Google Firebase (Firebase Authentication and Cloud Firestore) to store anonymous favorite records. Firebase is provided by Google LLC and is governed by Google's privacy policy: https://policies.google.com/privacy

Data retention

Local data on your device persists until you delete or uninstall the app.
Favorite records on our backend are retained as long as the app is in service. Because favorites are tied only to an anonymous Firebase user ID, we have no way to identify or contact you.
Feedback submissions are retained indefinitely, so we can track reported problems and requests over time. They are also delivered to the developer by email and will persist in that mailbox. If you sent feedback and want it deleted, email us at the address below — include enough of the original message for us to find it, since submissions are not linked to any account we can look you up by.

Your choices

Stop sharing favorites. Uninstalling the app stops any further data from being sent. Existing anonymous records cannot be linked back to you.
Delete favorites. Unfavoriting a song removes the corresponding record from your device and decrements the community count on our backend.
Send feedback anonymously. Leave the reply address blank. Your message is still delivered; we simply have no way to write back.
Don't send feedback at all. The feature is entirely opt-in — nothing is transmitted unless you write a message and tap Send.

Children's privacy

Songbook is not directed to children under 13. We do not knowingly collect information from children.

Changes to this policy

We may update this policy from time to time. The "Last updated" date at the top reflects the most recent revision. Continued use of the app after a revision constitutes acceptance of the updated policy.
