Data we process

The extension reads page content locally in your browser only when you choose Better View. wowMD Pro reads local .md files you open and stores annotations locally. Neither product uploads your Markdown documents or annotations. The website uses Google Analytics, which may process page URLs, browser or device identifiers, and cookies under Google's privacy policy.

Purpose and legal basis

Extension processing is limited to the reading features you request: outline navigation, section folding, code rendering, and table layout. Pro processing is limited to the reviewing features you use: structured reading, four-type annotations, an overall review map, cross-version re-anchoring, and the export formats you choose. Where GDPR applies, this is based on providing the service you request and legitimate interest in operating a privacy-preserving browser tool.

Storage and retention

wowMD does not maintain a remote database for reading or reviewing activity. The extension processes pages temporarily in the browser session, and wowMD Pro stores annotations, document fingerprints, versions, and settings in browser site data (IndexedDB). Feedback submissions are stored in Cloudflare D1 and include the submitted message, feature preferences, optional email address, page URL, user agent, and a hash derived from IP address and user agent. Feedback is retained until the maintainer deletes it.

Sharing and third parties

wowMD does not sell or share reading or annotation data. Exports are generated locally when you initiate them. Google Analytics is provided by Google, and website feedback is processed and stored with Cloudflare. Feedback information is used only to read feedback and follow up on requested features.

Data wowMD Pro stores locally

wowMD Pro stores the following data in your browser's site data (IndexedDB), never on a remote server: annotations you create (type, note, suggested replacement, context), document fingerprints used for cross-version re-anchoring, imported document copies for review, version history, and your preferences (theme, font size, layout). This data stays in your browser unless you choose to export it.

Pro exports and your data

All exports are generated locally in your browser when you initiate them. HTML export includes rendered Markdown with your highlights and notes visible. Reviewed Markdown includes your annotations as Obsidian callouts in a new .md file. Backup JSON contains your raw annotation data for backup or re-import. Ticket JSON includes a full document snapshot, your annotations, and section context — review this content before sharing it with an AI or third party.

Chrome Web Store and Limited Use

wowMD uses browser permissions only to provide the disclosed reading features. Information received from Google APIs, if any, will be used in accordance with the Chrome Web Store User Data Policy, including the Limited Use requirements.

Your rights

Depending on your location, including the European Economic Area, you may have rights to access, correct, delete, restrict, object to, or port personal data. Reading and annotation data remains in your browser; for a request about feedback information, contact the maintainer through the feedback form linked on this website.

Children

wowMD is not directed to children and does not knowingly collect personal information from children.

Changes

If wowMD changes its data practices, this policy will be updated before those changes are released.
