What we collect

• Account: your email address, your name and profile picture if you sign in with Google, and your preferences (voice, reading speed, reader theme).
• Documents: the PDFs you upload or import from arXiv, the text extracted from them, and your reading position, notes and bookmarks.
• Study content: when you use Professor Mode, the passage you select (or the section you ask a quiz or summary for) and what is generated from it.
• Usage: counts of documents, pages, audio generated and study requests, so that fair-use limits can be applied.
• Billing (Pro only): a reference to your customer record at Dodo Payments, your subscription's status, billing interval and renewal or end date, and the notifications Dodo sends us about it (see below). We do not receive or store your card number.
• Technical logs: request times, error codes and the account or document involved in a request, for diagnosing problems.

We do not use advertising or analytics trackers. We set only the cookies needed to keep you signed in (the anti-bot check described below may set its own).

How we use it

To turn your documents into audio and synced text, to remember where you stopped, to generate explanations and study aids when you ask for them, to apply usage limits, to send account emails (confirmation and password reset), and to keep the service secure and working. We do not sell your data and we do not use your documents to train models.

Who processes it for us

PaperVox runs on these services, which handle data on our behalf:

• Supabase: account sign-in and the database.
• Cloudflare: file storage (R2), delivery of audio files, DNS and incoming support email.
• Modal: the computers that read documents and generate speech.
• Vercel: hosting of the website.
• Google: sign in with Google, and the Gemini API that writes explanations, quizzes and summaries from the text you select.
• Cloudflare Turnstile: the anti-bot check on sign-up and sign-in. It runs in your browser and receives your IP address and browser details.
• Google Fonts: every page loads its icon font from Google Fonts, which receives your IP address and browser details.
• Resend: sending account emails.
• Dodo Payments: the merchant of record that sells Pro to you, takes your payment, collects tax and sends your invoice. It receives your name, email, billing country and payment details, and handles them under its own privacy policy.

Dodo's privacy policy is at https://dodopayments.com/privacy-policy.

Audio and study results are shared by content

To save cost, generated audio and generated study results are cached and reused when the same text is requested again, including by other people. They are stored under names derived from the text, not from your account, and they are not linked to you. Your uploaded PDF itself is stored privately and is only accessible to your account.

Keeping and deleting your data

Payment notifications from Dodo Payments (they include your email address and country) are kept for 90 days and then deleted. Your subscription record is deleted with your account; Dodo keeps its own records of payments, as it must for tax and accounting.

Deleting a document in the app removes the document, its extracted text, your notes, bookmarks and reading position, and the stored PDF. Uploads that fail or are abandoned are removed automatically. Cached audio and study results are not tied to you and are removed later when no document uses that text.

To delete your account and everything linked to it, email support@papervox.app from the address you signed up with.

Your choices

You can ask us for a copy of your data, to correct it, or to delete it by emailing support@papervox.app. You can stop using Google sign-in by using email and password instead.

Children

PaperVox is not intended for children under 13, and we do not knowingly collect their data.

Changes and contact

We will update this page when our practices change and change the date above.
