Privacy
What md2hd.com stores.
Hosted md2hd stores your account and the maps you save. Importing, parsing, and drawing happen in your browser. This policy names the data that leaves it.
- Markdown and maps
- Your browser reads imported files and turns them into a map. Hosted md2hd then saves the map to your account so you can open it on another device. A saved map includes its name, file paths, markdown text, card positions, and folder. A working copy also stays in this browser's
localStorage. - Account and workspace data
- We store your email address, name and avatar if provided, workspace memberships and roles, pending invitations, account plan, and storage use across workspaces you own. For paid accounts, we store the customer and subscription identifiers Stripe gives us. Card details never reach md2hd.
- Analytics
- Google Analytics receives page views and eight product events: account creation, sign-in, import, map creation, public-link creation and revocation, checkout, and purchase. Event details are limited to counts and categories such as file count, card count, plan, and billing interval. We do not send markdown, file names, map titles, card titles, or email addresses. Shared and invitation URLs are excluded from analytics. Signed-in events use a random account ID so one account is not counted as several people.
- AI services
- md2hd.com does not send your map content to an AI service or use it to train a model. If you use the separate md2hd skill with an AI agent, that agent handles the prompt and markdown under its own privacy terms.
- Cookies and browser storage
- Functional cookies keep you signed in, remember the active workspace, and tell static pages whether to show a sign-in or app link. Older password-protected public links use a short-lived access cookie. Google Analytics may set
_gaand_ga_*. Advertising storage and personalization are disabled. In the EEA, UK, and Switzerland, analytics storage defaults to denied and Google may receive cookieless measurement pings. - Public links
- Maps are private until an editor publishes a link. Anyone with a live link can read the complete map without an account. Public links are excluded from search indexing and stop working when revoked or when its owner's account leaves Pro. If your account returns to Free, your owned maps and extra workspaces remain stored and editable, public links stop, you cannot create another workspace, and access to workspaces owned by other people is suspended.
Services
Who receives data.
Each provider has one defined job.
- Vercel
- Hosts md2hd.com and processes web requests. Operational logs can include request metadata such as IP address, browser, path, time, and response status.
- Supabase
- Provides authentication and the database that holds accounts and saved maps. The project is deployed in its selected region, protected by row-level access rules, and encrypted at rest.
- Stripe
- Handles checkout, payment methods, invoices, and subscriptions. Stripe receives billing details directly. md2hd stores only its customer and subscription identifiers.
- Resend
- Delivers account, workspace, and plan emails. It receives the destination address and message contents.
- Google Analytics
- Measures the pages and product events listed above. Advertising features, ad personalization, session recording, and A/B testing are not used.
- Google Fonts
- Serves Inter and IBM Plex Mono. The font request tells Google your IP address and browser information.
Control
Export, correction, and deletion.
- Export
- A map is markdown. Open a card's markdown view to copy or save the source. There is no proprietary project format.
- Deleting a map
- Deleting an individual map removes it from the active workspace and frees account storage for the workspace owner. The database row remains recoverable until its workspace or owning account is deleted.
- Deleting an account
- Account deletion removes your profile, workspaces you own, their maps and public links, and cancels active subscriptions. Workspaces owned by someone else continue without you. Account deletion cannot be undone.
- Access and correction
- Settings shows the account and workspace data you can edit directly. For an access, correction, deletion, or privacy request, emailcontact@md2hd.com.
- Retention
- Account and saved-map data remains until deleted as described above. Providers may keep operational logs and billing records under their own retention policies and legal obligations.
- Children
- md2hd is not intended for children under 13, and we do not knowingly create accounts for them.
