Privacy Policy for PDF to PPTX Converter

Last updated: November 7, 2026

PDF to PPTX Converter (com.qelvox.pdftopptx) is provided by Bekrine LLC under the Qelvox brand.

Your documents stay on your device

The app reads only PDFs you select with the Android document picker or explicitly share from another app. It creates a temporary local copy and stores resulting presentations in private app storage. You choose original page images or optional Pro editable-text OCR. OCR uses a bundled Google ML Kit Latin-script model on your device, without a first-use model download. It creates simple editable text boxes rather than reconstructing photos, tables, charts or exact fonts. We do not upload your PDFs, page images, file names, recognized text or presentations to our servers. ML Kit processes recognition inputs and outputs on-device and does not send those contents to Google. A cloud document provider you choose may download or upload files under its own privacy policy.

Local history, settings and free exports

The app stores presentation names, output modes, creation times, slide counts, file sizes, presentation files, and your slide-size preference locally. Recognized text is stored inside editable presentations; a limited text preview is held in memory for review after conversion. A separate local ledger stores document fingerprints and conversion options to recognize previously unlocked presentations and maintain the three-free-personal-image-export allowance. Successful personal OCR exports also unlock the matching image alternative. These records are not transmitted to us. Deleting history does not reset the allowance or remove unlock records. Temporary files can be cleared in Settings; interrupted temporary work is removed when the app starts again. Clearing Android app storage or uninstalling removes the app’s local data. App backups are disabled.

Purchases

Optional monthly and yearly auto-renewing Pro subscriptions use Google Play Billing. Google processes payment and account information under its own policies. The app receives purchase status, purchase tokens and signed purchase information to verify entitlement, acknowledge purchases and restore access. We do not receive your card or banking details. Current purchase information is checked with Google Play; connecting to Google Play requires network access. See https://policies.google.com/privacy and https://play.google.com/about/play-terms/.

Google SDK diagnostics and no advertising

Google Play Billing includes diagnostic logging and can transmit billing API usage, success/failure results, service connection information, and associated app/device or billing-session information to Google to operate, secure and improve billing. This can occur when the billing client connects, including before a purchase. Google manages this information under its own policies. The converter does not send your PDF contents or presentation contents to Google.

Google ML Kit may send device manufacturer/model and OS information, app package/version, per-installation identifiers, performance measurements, image format/resolution and input/output sizes, SDK/model versions, feature events and error codes to Google for operational diagnostics and SDK usage analytics. SDK feature events can indicate use of OCR. This is technical information, not your document images or recognized text. Metrics may be queued offline and sent over HTTPS when connectivity returns. See https://developers.google.com/ml-kit/terms and https://developers.google.com/ml-kit/android-data-disclosure.

We do not add advertising, Firebase Analytics, or a developer-operated app-usage analytics or crash-report upload service. Google SDKs have the operational collection described above. We do not sell your personal information or use your files for advertising or AI training. Android, Google Play, and your chosen file providers may process information independently under their own policies.

Saving and sharing

Saving a copy writes it to the destination you select. Sharing or opening a presentation grants the app you select access to that presentation. Those services control their own handling of the file. Deleting app history does not delete copies you saved or shared elsewhere.

Support and your choices

If you contact support, we receive the information you choose to send and use it to respond. Do not send confidential documents unless you intend to share them. You can delete local history and temporary files within Settings or remove all local app data using Android settings. For requests about information you sent to support, contact [email protected]. Payment records held by Google are managed through Google.

Security and children

Documents are held in Android private app storage until you export them. Local storage is protected by your device’s security; no system is completely secure. The app is intended for general productivity and is not directed to children under 13. We do not knowingly collect children’s personal information.

Changes and contact

We will update this page and its date when the app’s behavior or this policy changes.
