Privacy Policy

Markstitch for iPhone and iPad · Effective 14 November 2026

Who we are

Markstitch is developed by Serigzhan Naviy, an individual entrepreneur in Astana, Kazakhstan, publishing as Appaq Labs (“we”, “us”). Contact: support@appaq.dev.

What stays on your device

To work, the app keeps these on your phone or iPad, in its own storage:

• the PDF patterns you open in it, and the charts it reads from them;
• your progress: stitches marked, stitching days, parked threads, highlighter marks;
• settings, such as which tips you have already seen.

None of this is sent to us or to anyone else. We have no copy of it and cannot see it. Deleting a pattern in the app, or deleting the app, removes it from the device.

What we collect

Nothing. The app makes no network requests of its own: no analytics, crash reporting, advertising or tracking, and no third-party code that does. In the App Store’s terms, this app’s privacy label is “Data Not Collected”.

Purchases

The one-time unlock is sold through the App Store. Apple handles the payment; we never see your name, card or Apple ID. The app only asks the App Store whether the unlock was bought, so it can come back when you restore it on another device. Apple’s own privacy policy covers what Apple does with purchase data.

Backups you make

With the unlock you can save a backup file of your patterns and progress. The app hands that file to the system share sheet, and you choose where it goes: Files, iCloud Drive, Google Drive, AirDrop or elsewhere. Wherever you put it, that service’s own terms and privacy policy apply. We never receive it.

When you write to us

If you email support, we get your email address and whatever you choose to send, such as a description or a pattern file that won’t open. We use it only to answer you and to fix the problem, never for marketing, and we delete pattern files once the problem is solved.

This website

This site uses no cookies, analytics or trackers, and its fonts are served from here rather than from a third party. It is hosted on Cloudflare, which processes visitors’ IP addresses to deliver the pages and protect them from attacks, under Cloudflare’s privacy policy.

Children

Markstitch is not aimed at children under 13, and it collects no data from anyone, children included.

Your rights

Because we hold no personal data about users of the app, there is nothing for us to access, correct, export or delete. For data in emails you sent us, write to support@appaq.dev and we will delete it.

Changes

If this policy changes, the new version will be posted here with a new effective date. If the app ever starts collecting any data, we will say so here and in the app before it does.
