Terms of Service for PDF to PPTX Converter

Last updated: November 7, 2026

Provider and service

Bekrine LLC provides PDF to PPTX Converter (com.qelvox.pdftopptx) under the Qelvox brand. These terms describe your use of the app. Contact [email protected] with questions.

The app offers two offline output modes. Original page images preserve each selected page as an image; their text is not editable. Optional Pro editable-text OCR uses bundled Latin-script recognition, including English and French, to create simple editable text boxes. It does not recreate photos, tables, charts, exact fonts or the complete original layout. Arabic and other non-Latin scripts are not supported by this OCR version. Recognition may contain errors; review and correct output before relying on it. A page without recognized Latin-script text may require image mode or a different page selection. Rendering and compatibility can vary with source PDFs, device resources, and presentation software. The app supports PDFs up to 150 MB, up to 10,000 source pages, and up to 500 selected pages per presentation. Password-protected or invalid PDFs may not be supported. Both modes use the same technical limits.

Free exports

Each installation includes three successful personal image-mode exports. New personal OCR exports require Pro. An export is successful when the PPTX is stored in the app’s History and available to open, save or share. Failed or cancelled conversions do not use a credit. Sample conversions in either mode are always free. Saving or sharing an already unlocked presentation does not use another credit. Re-creating an unlocked presentation with the identical PDF, page selection, slide size and output mode is free. After a successful personal OCR export, its image alternative with the same PDF, pages and slide size is also unlocked without another credit, including if the subscription later expires. Both files may be kept in History; creating an alternative does not automatically delete the first file. A different PDF, page selection or slide size is a new presentation. Deleting history does not reset free credits or remove local unlock records. Clearing Android app data or uninstalling removes local files, credits and unlock records. The app does not offer an account-based backup of them.

Optional Pro subscriptions

Pro provides unlimited personal image exports and new personal editable-text OCR exports subject to the limitations above. Monthly and yearly auto-renewing plans are offered through Google Play when available. The app displays the actual localized total price and billing period supplied by Google Play before checkout. No paid subscription starts merely by using the three free image exports or a sample; you must confirm a Google Play purchase.

Payment is charged to your Google Play account. Subscriptions automatically renew each month or year at the disclosed price unless cancelled before renewal. Manage or cancel from the app’s Manage subscriptions link or Google Play > Payments and subscriptions > Subscriptions. Uninstalling the app or deleting history does not cancel a subscription. When you cancel renewal, access continues for the period already paid, subject to Google Play’s purchase status and applicable policies. Refunds are handled according to Google Play policies and applicable consumer law.

Restore purchases checks the Google Play account that purchased the subscription. Internet access and a compatible Google Play installation are required to buy, confirm and restore Pro. Conversion itself runs locally. Local presentation history is not restored by restoring purchases.

Your files and responsibilities

You retain ownership of your documents and presentations. Process only files you are entitled to use, and respect others’ intellectual property and privacy. Keep independent backups of important originals and saved exports. Local presentations can be lost if you delete them, clear app data, uninstall, or lose access to the device. Opening, saving or sharing with other providers is subject to their terms and policies.

Availability and rights

We may update the app to maintain compatibility or correct problems. We do not guarantee that every PDF will convert or that output will meet a particular purpose. Nothing in these terms excludes rights, remedies, warranties or responsibilities that cannot lawfully be excluded under applicable consumer law. The app is intended for general productivity and is not directed to children under 13.

Privacy, updates and contact

The privacy policy describes local storage and Google Play purchases: https://qelvox.bekrine.com/privacy/pdf-to-pptx-converter. We will update this page and its date when the terms change.
