Privacy policy

Last updated: November 8, 2026

This policy explains what data Briefvox uses, why it uses it and how you can delete it.

How to contact us

Briefvox is an app that turns recordings and documents into notes, summaries and tasks. For questions about your data, write to support@briefvox.app.

Your notes stay on your phone

Recordings, imported files, transcripts, summaries, tasks and chats are stored on your device. Briefvox has no account and no cloud library: we do not upload or sync your notes. Android automatic backup of the app's internal data is disabled; backups you export yourself are files you control.

Briefvox uses the microphone only while you record, and notifications to tell you when a note is ready. You can revoke these permissions in Android settings. Briefvox does not request contacts or location, and has no ads or behavioral analytics.

When you use AI

Only when you transcribe, summarize, translate, ask about a note, extract tasks or read a PDF page with AI, the audio, text or page image you chose is sent, encrypted, through our service to an AI provider (currently OpenAI) to produce the result. If you turn on live transcription, the audio is sent, encrypted, directly from your phone to the same provider with a temporary credential that our service issues after checking your membership; that audio does not pass through our service. We do not send your name or email. The content itself may include personal information about you or others.

Our service does not keep the content after returning the result. Under the provider's current API terms, content is not used to train its models by default and may be kept in its security logs for up to 30 days, or longer for safety or legal reasons. See OpenAI's privacy policy. AI can make mistakes: review important results.

Purchases and membership records

Google Play processes payments. Briefvox receives a purchase token and confirmation data such as the product, plan, status and relevant dates. We use them to activate Briefvox PRO, restore valid purchases and apply renewals, cancellations and refunds. We do not receive your card details, name or email.

On our service we store a one-way fingerprint of the purchase token, the membership status and expiry, and usage records without content (request time, type, audio seconds and text size) to apply fair-use limits and prevent abuse. We keep these records while the membership is active and for up to 12 months after it ends.

Technical information from Google components

The Google Play billing component may automatically send technical information to Google, such as app and system versions, device characteristics, errors and connection events, even if you do not buy anything. Google processes it under the Google privacy policy.

Service providers

Cloudflare hosts our service and this website and may process connection data (such as IP address and time) for a short period to operate and protect them. Our providers may process data outside your country.

Deleting your data

• On your phone: delete notes in the app (they go to the trash first), or uninstall Briefvox or clear its data to remove everything stored by the app. Exported files and backups must be deleted where you saved them.
• On our service: write to us with your Google Play order number (it starts with GPA.) and we will delete the records linked to that purchase. We keep only minimal one-way fingerprints needed to stop a refunded or used purchase from being reused.
• Uninstalling Briefvox does not cancel a subscription. Manage it in Google Play.

Children

Briefvox is not directed to children under 13.

We will publish changes to this policy on this page and update the relevant notices in the app.
