Privacy and data

For the extension’s detailed disclosures and privacy contact, see the browser extension privacy policy.

Browser extension

The extension acts only when you submit the current page. It does not continuously send your browsing history. It submits the selected public page URL and destination choices required for the requested reading-list or EPUB operation.

Browser-local storage keeps the extension session and remembered destination preferences. Signing out removes the extension's local account session from that browser profile.

Content processing

• Public article pages and feed entries are fetched by the service for extraction.
• Newsletter messages are received through the private subscription inbox and sanitized for use as chapters.
• The original raw newsletter email is retained in private object storage for operational diagnosis. It can contain ordinary attachment data even though those attachments are not parsed or included in the EPUB.
• Generated EPUBs are retained in the account library until archived or deleted according to the available controls.
• Content-policy exclusions are recorded as Not attempted rather than silently bypassed.

Deleting your account

You can delete your account yourself from Account → Delete account on the website, or from Settings → Delete account in the mobile app. Deletion cancels any paid subscription immediately, removes your account record, reading lists, sources, devices, documents, and connected apps, deletes the generated EPUBs and raw newsletter emails held in private object storage, and signs you out everywhere. See Account and passkeys.

Operational logs that contain only reason codes and technical context may persist for their normal retention period. Payment records held by Stripe follow Stripe's own retention policy.

Diagnostics

Operational events and error monitoring are designed to use reason codes, operation outcomes, and technical context instead of article bodies, account tokens, or private browser data. Do not put sensitive content into a manual problem report.

The public Sentry DSN embedded in a web or extension build is a routing identifier, not an account administration secret. Sentry organization auth tokens are build or deployment secrets and must never be bundled into client code or documentation.

Third-party delivery

When a book is sent, the destination email and EPUB pass through the configured email and device provider. Amazon, Kobo-related services, Stripe, and other third parties apply their own privacy and retention policies to the operations they control.

The extension policy covers extension-initiated operations. A comprehensive service policy covering newsletter storage, website analytics, billing, and their retention periods remains separate work. Email [email protected] for privacy questions.
