ConvertMaster Ultra is developed by Hasnain Studio X with a local‑first, privacy‑first design philosophy. Every conversion runs on your device.
Effective date: 30 July 2026 · Publisher: Hasnain Butt Akhtar / Hasnain Studio X · Applies to: ConvertMaster Ultra for Android (com.convertmaster.app), version 0.3.0
ConvertMaster Ultra converts and compresses video, audio, image and PDF files entirely on your device, using an on‑device media engine.
All conversion happens locally. Files you pick are read locally and results are written locally.
ConvertMaster Ultra does not collect, store, or send any of the following:
No name, email, phone number, address, or account. The app has no sign in.
No screen views, session lengths, feature counters, or behavioural events.
The videos, audio, images and PDFs you convert are never uploaded, copied off device, or inspected remotely.
No contacts, calendar, call logs, SMS, clipboard monitoring, or installed app list.
No location permission is requested and no location is derived.
We run no server of our own, so your media cannot be uploaded even by accident. The only outbound calls the app can make are listed in section 4.
Theme mode, accent, reduced effects, haptics, and job queue concurrency, stored in the app private preferences.
Files produced by a conversion, plus a local database of job and output records so the Queue and Library can list them.
Temporary working files created during a conversion, held in the app private storage.
A local flag recording whether the one‑time Pro unlock is active, plus any temporary rewarded unlock window.
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.
These are the only outbound calls the app can make, and exactly what each one sends.
When you buy or restore the Pro unlock, 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.
Purchases are processed by Google Play. See section 5.
Builds with advertising enabled show Google AdMob ads, which use the Android Advertising ID and standard ad request data. Ads never receive your media or your file names. The Pro unlock removes advertising.
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.
The app receives only a purchase token confirming that a purchase occurred, which it uses to unlock Pro features.
Used only to read the files you pick for a conversion and to write the result. The app does not scan or index your library in the background.
Used for purchase validation and, in builds with advertising enabled, for ad requests. 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 0.3.0, effective 30 July 2026. Any change will remain consistent with our core principle: your data stays on your device.
