Summary: Tansura has no accounts, developer server, analytics, advertising, or cloud history. Raw pluck audio remains in memory for one visible capture and is never saved or sent.
Who provides Tansura
Tansura is provided by Saifullah Ahad. Privacy and safety questions: [email protected]. Website: https://saifullah.ai.
Microphone
After you tap to start and approve a prominent disclosure, Tansura records a short foreground window containing an ambient baseline and one pluck. Processing happens on your device. Raw samples are cleared best-effort immediately after analysis or cancellation and are never written to a file, exported, backed up, or transmitted.
Nearby sessions
If you deliberately join nearby people, Tansura exchanges device and line labels, derived frequency intervals and declared spans, quality/profile metadata, consent/reference operations, temporary public keys, and signatures. Local Wi-Fi or a user-created hotspot, Bluetooth, or alternating QR frames may carry this information. During setup, the device label and public pairing data are visible to nearby recipients before encryption begins. Use a landmark label rather than personal information. Measurement operations are encrypted after pairing and authoritative operations are individually signed. The developer operates no server and receives none of this data.
Camera, Bluetooth, and network permissions
The camera is active only while scanning a Tansura QR and no image is saved. Nearby Devices/Bluetooth is optional. Android 11 and earlier may label Bluetooth discovery as Location permission; Tansura does not request coordinates, infer location, or store location. Internet and network permissions support local sockets on the endpoint you scan; Tansura has no developer backend.
Storage and retention
Active lines, evidence, results, temporary peers, and keys are kept in memory by default. Preferences remain privately on your device until reset or uninstall. Optional recovery is off by default; if enabled, a derived run snapshot is encrypted with Android Keystore, excluded from backup, and deleted on close, clear, authentication failure, or expiry within four hours. It never contains raw audio or session traffic keys.
Export and deletion
Text or JSON leaves Tansura only after you preview it and choose an Android share destination. Exports omit audio, keys, session IDs, network addresses, participant IDs, and device identifiers. You can withdraw your active trial, end and erase a run, clear preferences, or uninstall. Tansura disables Android backup and device-to-device transfer.
Children
Tansura is not directed to children. It has no profiles, public posts, stranger discovery, or chat. An adult must manage every physical line. See the Tansura Child Safety Standards.
Security and limits
Temporary sessions use modern Android and Java cryptographic primitives, but no software can protect a compromised or unlocked phone, prevent a recipient from photographing a screen, or prove a physical statement. Tansura is not a force or safety measurement.
Your controls
You can deny or revoke microphone, camera, nearby-device, or legacy Bluetooth discovery permission in Android Settings. Features that depend on a denied permission remain unavailable. Ending and erasing a run clears the active local session; clearing app storage or uninstalling removes preferences and any optional recovery snapshot.
International transfers and sale
The developer receives no app data, so Tansura does not sell personal data or transfer it through a developer service. A nearby peer you deliberately connect can receive only the derived session information described above.
Changes
Material changes to permissions, collection, transport, analytics, or retention require this policy and the in-app disclosure to be updated before release. The latest policy remains at https://privacy.saifullah.ai/tansura.html.
