Privacy Policy

Overview

This Privacy Policy describes the data PitchShift uses to provide app functionality. Data is not linked to your identity. We do not track you across apps or websites, and we do not use the data for advertising.

Data used for app functionality

PitchShift may record and process the following categories on or through the app, solely to provide the product:

• Audio
• Photos and videos
• User content (for example lyrics you type or that the app writes for you, and song titles)
• User ID
• Device ID
• Purchase history

These identifiers are not linked to your name, email, or other real-world identity. We do not sell this data and we do not use it for tracking.

Features that work only on your iPhone

Changing key and tempo, and Find my key, run on your device. Find my key uses the microphone to listen while you sing or hum for 10 to 20 seconds; that recording is analysed on your iPhone and is never uploaded.

Automatic lyrics and song names

These features run only when you ask for them (for example by tapping “Write lyrics automatically”).

• Lyrics. The app sends the song's separated vocal track to our server, which forwards it to a speech-to-text provider and returns time-synced lyrics. English and most other languages are transcribed by Groq (Whisper). Arabic-script songs are transcribed by Google (Gemini API). The lyrics are saved in your library on your device. Our server does not keep the audio or the lyrics.
• Song names. If Apple's ShazamKit can't recognise a song (for example a cover), the app may send the first few lines of the transcript (up to 80 words) to our server. The server asks Google (Gemini API, which may use Google Search) for a likely title and artist, then checks the guess against LRCLIB, a public lyrics database. The app only suggests a name that passes this check, and you decide whether to use it. LRCLIB receives only the guessed title and artist, never your audio. Our server keeps a short-lived, in-memory record of the result, keyed by a one-way hash of the transcript, so repeat requests are fast. It is cleared whenever the server restarts.

No tracking

PitchShift does not track you. There is no advertising identifier collection, no data-broker sharing, and no cross-app tracking.

Third parties

Apple processes App Store distribution and in-app purchases. Purchase history is used only to unlock paid features you bought. Processors that help deliver a feature you request handle data only as needed for that request:

• Replicate: splits a song into parts (vocals, drums, bass, other).
• Apify: fetches audio when you import from a link.
• RevenueCat: validates purchases and restores Pro.
• Groq: transcribes vocals into lyrics. Groq does not use the audio or the lyrics to train models, and does not keep them, except temporary logs (up to 30 days) when it investigates errors or abuse.
• Google (Gemini API): transcribes Arabic vocals and suggests song names. We use Google's paid service: Google does not use the audio or the text to improve its products. Google keeps requests for a limited time (currently up to 55 days) to detect abuse, and up to 30 days when Google Search is used to find a song name.
• LRCLIB (lrclib.net): a public lyrics database used to confirm a suggested title and artist.
• Apple ShazamKit: suggests a song's title after import.
• Vibecode: hosts our server.

If you enter your own Replicate or Apify API key (About > Use my own keys), the app sends the audio straight to that service under your own account.

Retention

Audio processed to return a result is not kept except as needed to provide that result or a feature you enable (such as a library backup keyed by an anonymous identifier). Our server does not store lyrics or transcripts. It keeps only per-device daily usage counts for automatic lyrics and song names, and resets them daily. You can delete content in the app. Uninstalling the app removes locally stored data.

Deleting your data and account

PitchShift has no sign-in and no user account. The app uses a random, anonymous identifier stored on your iPhone to back up your library, count free uses, and restore Pro purchases. It is not linked to your name or email.

• In the app: open Library and swipe left on a track, then tap Delete. To delete everything, tap the trash icon at the top of Library and confirm. Deleting a track also deletes its backup copy from our server.
• On your iPhone: uninstalling the app removes the library stored on your device. The anonymous identifier stays in your iPhone's Keychain so a backup can be restored if you reinstall, so delete your library in the app first if you want the server copies gone.
• By email: to ask us to delete all data tied to your identifier (library backups, usage counts and purchase records), email support@smbdmtechnologies.com with the subject “Delete my PitchShift data”. If you bought Pro, include the order ID from your Apple receipt so we can find your records. We delete them and confirm by reply within 30 days. If you never bought Pro, nothing links your data to you, so deleting your library in the app is the way to remove it.

Apple keeps its own records of App Store purchases. Subscriptions are managed and cancelled in your Apple account settings.

Children

The app is not directed to children under 13 (or the minimum age required in your country), and we do not knowingly collect personal information from children.

Changes

We may update this Privacy Policy. Material changes are shown by updating the effective date above.
