Privacy Policy - Metriloq

Metriloq works fully offline. Practice recordings, passages, notes, and timing evidence stay in private app storage on your Android device. Metriloq does not collect, transmit, sell, or share them.

1) Who we are

Metriloq is provided by Saifullah Ahad. Privacy contact: [email protected].

2) Information handled on your device

When you choose to calibrate, Metriloq briefly reads microphone input to estimate the ambient room baseline. When you start a practice recording, it records a mono WAV audio file and analyzes small audio frames locally to estimate voiced time, speaking runs, pauses, rhythm consistency, dynamic range, and signal quality.

You may write passages and save session context, comfort ratings, private notes, waveform envelopes, segment timing, and markers. You may also import a compatible WAV file that you select through Android's document picker. These items remain in Metriloq's private on-device storage.

3) How information is used

The information is used only to play back your chosen recording, show transparent timing evidence, maintain your private session library, and compare repeated practice sessions. Metriloq provides descriptive self-practice estimates; it is not a medical device, diagnosis, treatment, or substitute for a qualified speech-language professional.

4) Permissions and connectivity

Metriloq requests the Android RECORD_AUDIO permission only when you choose calibration or recording. The microphone is not used in the background. WAV import and export use Android's system document picker and do not require broad storage access.

The app declares no INTERNET, network-state, location, photos, camera, contacts, phone, SMS, notification, advertising ID, or ad-services permission. Metriloq has no account, cloud sync, analytics, advertising, tracking, crash-reporting SDK, developer server, or third-party data service.

5) User-directed files

When you choose CSV or PDF export, JSON backup, JSON restore, or WAV import, Android's document picker lets you select the source or destination. Metriloq reads or writes only the file you select and does not upload it. JSON backups contain passages, metrics, context, ratings, notes, and markers, but intentionally do not include recording audio.

6) Data collection and sharing

We do not receive or share your recordings, passages, timing evidence, ratings, context, notes, imported files, or exports because Metriloq has no network access. Data leaves private app storage only when you deliberately export a file to a destination you choose.

7) Retention and deletion

Saved passages and sessions remain in Metriloq's private storage until you delete a session, restore a different backup, clear Metriloq's storage in Android settings, or uninstall the app. Deleting a session also removes its private recording file. Exported and backup files remain at the location you selected until you delete them separately.

8) Security and device backup

Metriloq stores its database and recording files inside Android's app-private storage and disables Android Auto Backup. No developer copy exists. Your device access controls, operating-system security, and any destination you select for exported files affect the security of information on your device.

9) Children's privacy

Metriloq is intended for adults aged 18 and over and is not directed to children under 13. Because it has no server or account, the developer does not knowingly collect personal information from children.

10) Changes to this policy

We may update this policy if Metriloq's behavior changes. The current version remains available at privacy.saifullah.ai/metriloq.html, with the effective date updated above.
