Privacy policy

Last updated: 20 October 2026

Bookworm ("we", "us") is an AI book-summary service available at bookworm.vivekkhare.org and as an Android app. It is operated by Dr. Vivek Khare, India. This policy explains what we collect, why, who we share it with, and your choices. Contact: support@vivekkhare.org.

What we collect

• Account data: email address, a username, and — if you use Google sign-in — your Google account ID and profile picture URL.
• Content you upload: books and documents (PDF, EPUB, DOCX, TXT and similar) and the text extracted from them.
• Content we generate for you: summaries, audio narrations, flashcards and chat answers.
• Usage data: which features you use, summary counts and dates, your plan, and IP address in server and activity logs.
• Payment data: plan, amount, date and payment reference. Card, UPI and bank details are entered on Razorpay and never reach our servers.

How we use it

To sign you in, generate the summaries and audio you ask for, enforce plan limits, process payments, prevent abuse (including automated screening of uploads), fix problems, and contact you about your account. We do not sell your data and do not show ads.

Who we share it with

• Anthropic — text from your uploads and book details are sent to Anthropic's Claude API to generate summaries and screen uploads.
• Google — Google sign-in; Google Cloud Text-to-Speech receives summary text to create audio; Google Books receives book titles for metadata lookup.
• Razorpay — processes payments.
• Our hosting and email providers — store data and send sign-in codes.
• Content delivery networks (Tailwind, jsDelivr, unpkg, Google Fonts) load page styles and scripts and may see your IP address.
• Authorities, where the law requires it.

Security

Data is sent over HTTPS. Generated audio and uploads are reachable only by their owner when signed in. Sign-in uses one-time email codes or Google; we do not store passwords.

Retention and deletion

We keep your data while your account exists. You can delete your account at any time from Account → Delete my account in the app or website, or see bookworm.vivekkhare.org/delete-account. Deletion removes your profile and everything you uploaded or generated immediately. Payment records are kept, without your name or email, for as long as tax law requires. Server backups roll over within 30 days.

Your rights

You can access, correct or delete your data, or withdraw consent, by using the account page or emailing us. Under India's Digital Personal Data Protection Act, 2023 you may also raise a grievance with us at the email above.

Children

Bookworm is intended for users aged 18 and over. We do not knowingly collect data from children.

Changes

We'll update the date above when this policy changes and notify you by email of significant changes.
