Tabla Tuner Privacy Policy

The microphone

Tabla Tuner needs the microphone to do the one thing it does: hear your drum and work out its pitch. Audio is analysed live, on your device, one short buffer at a time, and each buffer is discarded the moment the next one arrives.

Nothing is recorded. There is no file, no buffer kept in memory after it has been measured, and no audio of any kind sent anywhere. The app has no code that could save or transmit a recording — you can decline the permission, and everything except the tuner still works.

Your settings

Your reference pitch, the tuning thresholds and the note you last selected are stored on your device using the system's own local storage. They stay there, they are not synced, and deleting the app removes them.

Anonymous usage measurement

Tabla Tuner sends a small, anonymous record to a server of ours so we can tell how many people are using the app and which versions are still running. That second part is what lets us know when an update is worth prompting for, and — in the rare case of a serious bug — when an old version needs to stop being used.

The record contains a random identifier generated on your device the first time the app runs, Apple's vendor identifier for this device, the app version and build, your iOS version, your device model (for example “iPhone15,2”), your language setting, and the country our server infers from your connection. Our own endpoint uses your IP address to work out that country and does not keep the address itself. It is sent at most once a day.

The random identifier is not your name, your Apple Account, or anything you have typed. It is created fresh if you delete and reinstall Tabla Tuner, so it identifies an installation rather than a person. Apple's vendor identifier is shared across apps from this same developer and resets once you delete all of them from your device.

The app also records when it is opened, installed or updated, which of our in-app messages you were shown and whether you tapped them, and which posts in What’s New you saw, opened or tapped. That last part is counted twice over: once on our own server, so a post can be credited with how many installations it reached, and once in PostHog, an analytics service acting on our behalf. Both carry the same anonymous identifier, the app and device details listed above, and nothing else about you.

PostHog receives the address your connection comes from, works out an approximate location from it — country, and often the region or city — and keeps both alongside the event. It is configured to store no user profiles, no session recordings and no crash data. That location is attached to the anonymous installation identifier, not to a person: there is no account here to attach it to.

None of it is advertising. We do not use an advertising identifier, we run no ads, we work with no ad networks or data brokers, and we never combine any of this with data from other companies. Under Apple's definition, Tabla Tuner does not track you — which is why the app never asks for tracking permission.

There is no switch for this in the current version, and that is a deliberate choice rather than an oversight. What is collected is anonymous, is never linked to you, and is not tracking under Apple’s definition — there is nothing in it to consent to and nothing about you to withhold. If an earlier version offered you a “Share anonymous usage” switch and you turned it off, it stays off. Deleting Tabla Tuner ends the collection completely in any version: a fresh install starts a new identifier, and the old one simply stops appearing.

Messages and What’s New

Tabla Tuner occasionally shows a message from us inside the app — an announcement, or a note that an update is available. Those are fetched when the app opens and shown on screen. They are not push notifications, they never reach you when the app is closed, and asking for one tells us nothing about you beyond the anonymous record described above.

What’s New is a tab of posts we publish — releases, videos, things worth saying. The app asks our server for the current list, keeps a copy on your device so the tab opens without a connection, and checks for changes occasionally. Asking for the list sends nothing about you; it is a plain request for public content that is identical for everybody.

Which posts you see, open or tap is recorded against the anonymous installation identifier described above, and sent to our server in a small batch. It is how we tell whether a post reached anyone. It records the post, not you: there is no reading history, no time spent, and nothing that could be turned back into a person.

Song key lookup

The Songs tab finds the musical key of a recording so you can tune to it. When you search, the words you type are sent to our server along with the anonymous installation identifier described above. The server asks Spotify’s catalogue for matching songs and sends the results back. Spotify receives the search from our server, not from your device, and is told nothing about you.

The words you searched for stay on our own server, where they are kept so we can see which songs people are looking for. Our analytics service is told only how many characters you typed and how many results came back — never the search itself.

Asking us to analyse a song records which installation asked for which song. That is what enforces the daily limit on live analyses, and it is what decides which songs get analysed next: the ones the most people asked for. If you tap a key to tune to it, or tell us whether a key matched the recording, that is recorded the same way — against the installation, not against you.

The key itself comes from third-party music-analysis services, which are asked about a song by its Spotify identifier or its standard recording code. They are never told who asked. Once a song has been analysed the answer is kept on our server and reused for everybody, so most songs are never looked up twice.

A song’s page can play a thirty-second preview. The clip is streamed straight from Apple or Deezer, whichever has it, so that company’s servers see your device’s network address the way any website you visit would. They are not told which installation asked, and nothing about the preview is recorded on our side.

Your recent searches and the songs you opened are also kept on your device so the tab works without a connection. Deleting the app removes that copy.

Tips and purchases

Tabla Tuner offers optional one-time tips. They unlock nothing: the app stays the same for everyone, and the daily limit on song analyses does not change for supporters. Payment is handled entirely by Apple; we never see your name, email, card details, or billing address.

To recognise a tip and restore it on a new device, the app uses RevenueCat, a purchase-infrastructure service. RevenueCat receives an anonymous identifier and the transaction details Apple provides — nothing that identifies you personally. Their handling of that data is described in the RevenueCat privacy policy at revenuecat.com/privacy. If you have tipped, that same anonymous purchase identifier is included in the usage record described above, so a tip can still be recognised if accounts are ever added, and the usage record notes that a tip was made and which tier — nothing more.

What Tabla Tuner does not do

No accounts and no sign-up. Nothing you have to buy: the tip is optional and unlocks nothing. No advertising, no ad networks, no advertising identifier. No tracking across other companies' apps or websites, and nothing sold or shared with data brokers. No audio kept, ever.

The third parties involved in running the app are Apple and RevenueCat (payment and tip restoration), PostHog (usage analytics), Supabase and Vercel, which host the server that receives the usage record, and — for the Songs tab only — Spotify, Deezer, Apple’s iTunes catalogue and the music-analysis services our server asks about a song (and, when you play a preview, Apple or Deezer serves the audio to your device directly). Each acts on our behalf under its own agreement; none of them is given anything that identifies you.

Children

Tabla Tuner is not directed at children and asks no one their age, because it has no accounts and collects nothing personal from anyone. The anonymous usage record identifies an installation, not a person, and is the same whoever is holding the device. A parent who wants it to stop can delete the app; a fresh install starts a new identifier, and the old one simply stops appearing.

Where we operate

Tabla Tuner is made in Montreal, Canada. The anonymous usage record is handled by services in the United States: our own endpoint on Vercel, a Supabase database, and PostHog. Because that record contains nothing that identifies you, there is nothing in it to look up, export or erase on request — but if you would like the row for your installation removed, write to us and we will delete it.

Changes to this policy

If Tabla Tuner ever adds a feature that changes how data is handled, this page will be updated before that feature ships, and the effective date below will move. Continued use of the app after a change means the updated policy applies.
