Privacy Policy

Last updated: 28 September 2026

What this policy covers

This policy applies to the Unmark website and to the Unmark app for Mac, iPhone and iPad. Unmark is a product by Curato Labs.

No account, no server

Unmark does not offer or require sign-in of any kind. There is no Unmark server. Nothing you convert is uploaded, and there is no history of your conversions anywhere, on our side or on yours.

Your clipboard

Clipboard content is never stored and never transmitted. It is converted in memory and written straight back to the clipboard.

On the Mac, the app reads the clipboard only when the popover is opened, when the hotkey is pressed, or when Auto-convert is on. At every other moment it is not reading your clipboard. When Auto-convert is on, the app checks whether the clipboard has changed and reads it only when it holds plain text that is not already rich text and was not written by Unmark itself.

On iPhone and iPad, the app reads the clipboard only when you tap Paste, and the share extension only receives the text you selected and shared into it.

Analytics

The app uses Google Firebase Analytics to understand how Unmark is used, for example that onboarding was finished, that a conversion happened, which style was chosen, or that the Pro screen was opened. Events carry the action and coarse details such as a word-count range or whether a document contained a table. They never carry your text, any part of it, or anything derived from its wording.

Firebase assigns a random app-instance identifier to your installation and receives the device model, operating system version and an approximate location derived from your IP address. This data is not linked to your identity, is not used to track you across other companies' apps or websites, and is not used for advertising. Unmark does not use the advertising identifier and does not show an App Tracking Transparency prompt. Google processes this data under the Firebase privacy terms.

Purchases

Unmark Pro is a one-time purchase handled by Apple through StoreKit and the App Store. We never see or store your payment details.

We use RevenueCat to record purchases and restores so we can report on sales. RevenueCat receives the purchase details Apple provides (the product, price, currency, date and an anonymous transaction record) together with a random identifier for your installation. We do not have accounts, so none of this is tied to your name or email. RevenueCat processes this data under its privacy policy.

Our other apps

The "More from Curato Labs" list is fetched from a static file so it can be kept current between releases. The request carries no information about you and no information about what you have converted.

Support email

If you write to support, we receive whatever you include in that email, such as your address, your device details and your message.

Sharing

We do not sell personal information, and we hold no clipboard content to sell or share in the first place. We may disclose limited information where the law requires it.

Children

Unmark is not directed to children under 13.

Changes to this policy

We may update this policy as Unmark changes. The latest version is always published at this URL with the revised date.
