Swar Saathi ("the app") is an Indian classical music practice app with a tanpura, taal metronome, tabla, alankar and raag practice, a pitch tuner and a recorder. It is made by Soumendra Mishra (Bansuri Parampara, bansuriparampara.in) ("we", "us"). This page explains what information the app uses and why.
Microphone. The app asks for permission to use the microphone for the Pitch Tuner, the "Listen - check my swar" feature and the Recordings feature. The sound is analysed on your device. Recordings you make are saved on your device (or in the folder you choose in Settings). We do not receive your recordings or your voice, and we do not upload them. They leave your device only if you choose to share or upload a recording yourself, for example with the Share button to WhatsApp, Google Drive or OneDrive.
Device ID for the free trial and unlock. To run the free trial and to unlock the full version, the app makes a Device ID from a fixed identifier of your phone or computer. When the app starts, it sends this Device ID, the type of device (for example Android or Windows) and the app version over an encrypted (HTTPS) connection to our trial register, which is a Google Sheet that we own and operate through Google Apps Script. We use it only to remember the date your trial started, so that reinstalling the app does not restart the trial, and to give you an unlock key if you have bought or been given one. We do not use it for advertising, and we do not sell or share it with anyone.
Things you create. The compositions, drafts, custom raags, recordings and settings you create in the app are stored on your device. We do not receive them.
Purchases. If you buy the full version, the payment is handled by Google Play (on Android) or the Microsoft Store (on Windows). We do not receive or store your card, UPI or bank details. Google or Microsoft tells the app whether the purchase succeeded.
The only information that leaves your device automatically is the Device ID, device type and app version described above, sent to our trial register. Google (Google Apps Script and Google Sheets) hosts that register for us. Recordings or files leave your device only when you choose to share them.
Everything you create stays on your device, and uninstalling the app removes it (except files you saved in a folder you chose yourself). The Device ID entry in the trial register is kept for as long as it is needed to run the trial and to unlock the full version. To have your entry deleted, email us at the address below with your Device ID (shown on the "Full version" screen in the app), and we will delete it. Deleting it may restart your free trial period.
The app is not directed at children under 13, and we do not knowingly collect personal information from children.
The connection to the trial register is encrypted. No system is perfectly secure, but we keep the information we hold to the minimum described on this page.
If we change what the app does with information, we will update this page and the date at the top.
