Privacy Policy

ConvertMaster Ultra converts and compresses video, audio and image files, and turns images into PDFs and PDF pages into images, entirely on your device, using an on‑device media engine.

• We do not collect personal data.
• We do not upload your media to any server.
• We operate no server that receives your files or your usage.
• We do not sell, share, or monetize user data.
• The app contains no analytics SDK and no crash reporting SDK.

All conversion happens locally. Files you pick are read locally and results are written locally.

Personal Identity Data

No name, email, phone number, address, or account. The app has no sign in.

Usage Data or Analytics

No screen views, session lengths, feature counters, or behavioural events.

User Content

The videos, audio, images and PDFs you convert are never uploaded, copied off device, or inspected remotely.

Sensitive System Data

No contacts, calendar, call logs, SMS, clipboard monitoring, or installed app list.

Location Data

No location permission is requested and no location is derived.

No server ever receives your media, so it cannot be uploaded even by accident. The only outbound calls the app can make are listed in section 4.

App Settings

Theme mode, accent, reduced effects, haptics, and job queue concurrency, stored in the app private preferences.

Your Outputs

Files produced by a conversion, plus a local database of job and output records so the Queue and Library can list them.

Local Cache

Temporary working files created during a conversion, and copies of the files you pick or share into the app, held in the app private storage. Picked copies are cleared when the app starts with no queued job that still needs them.

Local Licence State

A local flag recording whether the one‑time Pro unlock is active and when it was last confirmed, plus the Google Play purchase token while a purchase is waiting to be confirmed.

This data never leaves your device and is removed when you uninstall the app. Files you explicitly saved or shared elsewhere remain where you put them.

Purchase Validation

When you buy or restore the Pro unlock, and about once a week afterwards to re‑confirm it, the app sends the product id, the Google Play purchase token, and the app package name to a Hasnain Studio X validation endpoint so the purchase can be verified with Google Play. No media and no personal data are included.

Google Play Billing

Purchases are processed by Google Play. See section 5.

Google Fonts

The app’s typeface (Inter) is downloaded from Google Fonts the first time it is needed and then kept on the device. The request carries your IP address and standard request headers to Google. No media, file names or personal data are included.

Outbound Links

Opening the website, this policy, or the contact email hands off to your browser or mail app, which have their own policies.

The one‑time Pro unlock is sold through Google Play Billing. Google handles the entire payment flow.

• We do not process payment information.
• We do not store payment details.
• No card number or billing address ever reaches the app or the developer.
• We do not receive your Google account information.

The app receives only a purchase token confirming that a purchase occurred, which it uses to unlock Pro features.

Files and Media

The app requests no storage or media permission. Files you pick in the Android file picker, or share into the app from another app, are read for that conversion only. Results are written to the app private storage, and Save to device writes only to the place you choose. The app does not scan or index your library.

Internet and Network State

Used for purchase validation and to download the app’s typeface. It is never used to transmit your media.

No permission in this app is used to send your content anywhere. Conversion is entirely local.

ConvertMaster Ultra is a general audience utility. It is not directed to children under 13 and does not knowingly collect personal information from them. Because the app collects no personal information from anyone, there is nothing to delete on request.

This policy is updated whenever the app data behaviour changes, and the effective date and version at the top are updated with it. The current version corresponds to ConvertMaster Ultra 0.4.0, effective 6 October 2026. Any change will remain consistent with our core principle: your data stays on your device.
