onibakuTabfall privacy policy
Last updated 6 November 2026. Tabfall is made by Onibaku (admin@onibaku.co.uk). This policy covers Tabfall for iPhone and Android.
Where it runs
Tabfall runs on your phone. There's no Onibaku account, and it works offline. Unless you turn on Send my recordings, the only network traffic is the billing service of the App Store or Google Play, used to check and make the one-off purchase.
The microphone
Tabfall uses the mic to tell which notes you played, and in the tuner, level check and timing calibration. Sound is analysed in memory as it arrives and then discarded. Unless you turn on Send my recordings, it isn't recorded, saved to disk or sent anywhere, and we never receive it. The mic stops when the app goes to the background. You can refuse or withdraw mic access in your phone's settings; pieces can still be watched and heard.
Send my recordings (optional, from version 1.0.1)
This setting is off unless you turn it on in Settings, and the app asks you first. It's for people aged 16 or over. If you leave it off, nothing below applies to you.
What's sent. While it's on, each Play along or Wait run is recorded and a REC mark shows on screen. When you leave the results screen of a finished run, unless you tap "Don't send this one", the app sends over Wi-Fi: the recording, the piece and mode, each note's score, your audio route and timing setting, your phone model and app version, and a random ID made for this purpose. Recordings can pick up anything in the room, including voices, so turn it off if others are talking nearby.
Why, and our legal basis. We use recordings only to measure and improve how Tabfall hears guitars, including training its listening model. Our legal basis is your consent. We don't sell them, and we don't use them for advertising.
Where and how long. They go over an encrypted connection to a server Onibaku runs itself, and are kept for up to 2 years. Upload request logs are turned off; your IP address is held in memory for up to an hour to limit abuse, and isn't stored with recordings. Unsent recordings on your phone are deleted after 7 days.
Your choices. Turning the setting off stops recording and deletes anything not yet sent. "Delete everything I've sent" in Settings removes your recordings from our server straight away. A listening model already trained on a recording won't be retrained because of a deletion, though it doesn't contain the recording itself. You also have rights to access or erase your data and to complain to the Information Commissioner's Office (ico.org.uk). If you've lost access to the app, email us.
What it stores, on your phone
- Files you import and tabs you paste. Tabfall copies the notes into its own storage so you can open it again. They're never uploaded. Delete one from the library, and your original file isn't touched.
- Your results and settings. Best scores, timing calibration, backing level and similar choices.
- Whether you've unlocked the app.
On Android these are excluded from backups. On iPhone, your own iCloud or computer backup may include them. Uninstalling the app removes them.
Payments
The unlock is bought through the App Store or Google Play, so Apple or Google handles the payment under its own privacy policy. We receive only the anonymised sales reports each store gives every developer.
What it doesn't do
- No account, sign-in or contact details.
- No ads, analytics, crash reporting or tracking SDKs.
- No location, contacts or camera access.
- Nothing collected unless you turn on Send my recordings, and nothing shared with anyone else.
