TabToPrompt — Privacy Policy

Last updated: 27 September 2026

TabToPrompt ("the extension") is a Chrome extension that converts the content of the web page you're viewing, or the text you've selected, into Markdown. This page explains, plainly, what data the extension touches and what it does with it.

Short version

• We do not collect, transmit, or sell your browsing history, page content, or any personal data.
• Everything the extension does — reading the page, converting it, counting your free conversions, remembering your preferences — happens locally, in your own browser storage (chrome.storage.local).
• The only network request the extension ever makes is a license-key check against Polar.sh, and only when you activate a Pro license or the extension periodically re-checks a license you've already activated.
• No account, sign-up or login is required to use the Free tier.

What the extension reads

When you click "Convert page to Markdown," press the Alt+Shift+M shortcut, or use a Pro feature (merge tabs, table to CSV), the extension reads the HTML of the page you're currently on (or the tabs you explicitly selected, for the "merge tabs" Pro feature) to build the Markdown output. This happens entirely inside your browser, using locally bundled code (Mozilla's Readability library and Turndown) — no page content is ever sent to any server, including ours.

What is stored, and where

The extension stores the following in chrome.storage.local, which lives only on your device and is never synced to a server we operate:

• Your conversion preferences (e.g. include images, link style, front-matter defaults, custom prompt template).
• A daily counter of how many free conversions you've used (resets automatically at local midnight).
• If you activate Pro: your license key and the last time it was validated, so the extension can work offline for a short grace period without re-checking every time.

The one network call: Polar.sh license validation

Pro subscriptions are sold and billed by Polar.sh, acting as Merchant of Record — we never see or store your card details. When you paste a license key, or periodically (at most once every 24 hours) while a Pro license is active, the extension sends the license key and our public organization ID to Polar's license-validation endpoint (https://api.polar.sh/v1/customer-portal/license-keys/validate) to confirm the key is still valid. This request does not include any page content, browsing history, or personal information beyond the license key itself. See Polar's own privacy policy for how they handle that request.

Permissions, in plain language

• Read the current tab, on demand (activeTab, scripting) — only when you actively ask for a conversion; never in the background, never on every page.
• Local storage (storage) — to remember your settings and daily counter, on-device.
• Clipboard write (clipboardWrite) — to copy the Markdown you generated. We never read your clipboard.
• Downloads (downloads) — to save a .md or .csv file when you ask to download one.
• List of open tabs (optional tabs permission) — only requested if and when you use the Pro "merge open tabs" feature, and only after you explicitly grant it.

Children's privacy

TabToPrompt is not directed at children and does not knowingly collect data from anyone.
