Privacy
Short version: your writing stays on your Mac. We only handle what is needed to sell and activate licenses. The app doesn’t track what you do in it; it only tells manutius.app when it starts, so we can count installs. The website uses Google Analytics to count visits. No ads.
What the app does on your Mac
- Your books are files you save wherever you like. Backups are written to a folder on your Mac (or one you choose, such as iCloud Drive). We never receive them.
- Spelling and grammar checking runs entirely on your Mac.
- Listen downloads a voice model once from Hugging Face (huggingface.co) and then runs offline. That download reveals your IP address to Hugging Face, like any download.
- Updates: the app asks GitHub (github.com) whether a newer version exists, roughly at launch and every few hours. GitHub sees your IP address and the app version.
- License checks: after you activate, the app contacts manutius.app every few days to confirm the license. It sends your license key, an anonymous identifier for your Mac (a hash of its hardware ID), the app version, and your Mac’s name (so you can tell your activations apart). No book content is ever sent.
- Launch check-in: each time the app starts, it tells manutius.app the same anonymous Mac identifier, the app and macOS versions, whether your Mac is Apple silicon or Intel, and whether the app is licensed. We use this to keep the free trial to 14 days per Mac and to count how many Macs use Manutius and which versions they run. Nothing else is sent, and nothing identifies you personally.
- AI features (optional): if you use the Claude panel, the text you ask about — and, if you allow edits, the parts Claude edits — is sent to Anthropic through your own Claude account, under Anthropic’s privacy terms. If you connect another AI app through Assist (Cursor, Codex, Gemini CLI and so on), what that app reads goes to that app’s provider under its terms. Nothing is sent unless you use these features.
- Report a Problem opens an email in your mail app pre-filled with the app version, macOS version and the last lines of the app’s log. You see and edit it before sending; nothing is sent automatically.
What we store when you buy
- Stripe processes your payment. We never see your card number. Stripe shares with us your email address, the plan you bought, and Stripe’s identifiers for the payment, customer and subscription. Stripe’s own privacy policy covers its processing.
- We store your email address, license key, plan, subscription status and activation records (the anonymous Mac identifier, Mac name, app version and dates) in our database, hosted by Supabase in the United States.
- We send license and recovery emails through Resend from hello@manutius.app.
- Server logs (IP address, request path, timestamps) are kept briefly by our hosting provider, Vercel, for security and debugging.
When you ask for the download link by email
- We store your email address, the language of the page, the country your connection comes from, whether you agreed to occasional tips, tutorials and offers, and whether the link in the email was clicked. The email is sent through Resend.
- If you agreed, we may email you now and then about Manutius. Every such email has an unsubscribe link, and you can also write to hello@manutius.app. If you didn’t agree, we send the link and nothing else.
When you order printed copies
- Instant Print sends your book’s print files (the interior PDF and the cover) to our server and on to Lulu, which prints and ships the books. The files are kept in private storage at Supabase and are only reachable through links that expire.
- We store your name, shipping address, phone number and email with the order and pass them to Lulu for printing and delivery; couriers ask for the phone number. Stripe processes the payment as above.
- We keep order records as long as tax and accounting rules require, and delete print files when they are no longer needed for the order.
How long, and your rights
We keep purchase and license records for as long as your license is active and as long as tax and accounting rules require afterwards. You can ask us to see, correct or delete your data at hello@manutius.app; deleting a license record ends the license. We don’t sell or share your data with anyone except the processors named above (and Lulu, for print orders), and only to provide the service.
Website analytics and cookies
manutius.app uses Google Analytics to understand how many people visit and which pages they read. It sets cookies (_ga) to tell visits apart and sends your IP address, browser and page views to Google, under Google’s privacy policy. We don’t use it for advertising. If you arrive through a partner’s referral link, the site sets a first-party cookie (mnt_ref) that holds only that partner’s code for 60 days, so a purchase can be credited to them. It identifies no one. The site also counts page views itself, without cookies: it keeps the page, the country and a one-way hash that changes every day, so the same visitor counts once per day and no one can be identified afterwards. When you click a download button, we record which version (Apple silicon or Intel) and the country your connection comes from, to count downloads; not your IP address. If you visit from Europe, we ask before it loads, and it stays off if you say no. Stripe Checkout sets cookies on its own pages for fraud prevention and to remember Link accounts.
Children
Manutius is not directed at children under 16 and we don’t knowingly collect their data.
