What is Tessera?

Tessera is a daily-practice app for learning financial accounting, the "Duolingo of accounting." Short lessons build real fluency with debits, credits, and the financial statements, taught through the story of one business you watch grow. It is designed for five minutes of practice a day.

Does it work offline?

Yes. Tessera runs entirely on your device and needs no internet connection to practice. Your progress is saved locally.

How does the subscription work?

Module 1 is free to practice for as long as you like. A single subscription unlocks the full curriculum. The subscription is billed monthly through your Apple ID and renews automatically until you cancel. You can review the full Terms of Use and our Privacy Policy any time.

How do I cancel or manage my subscription?

Subscriptions are managed by Apple, not inside Tessera. On your iPhone, open Settings > your name > Subscriptions, select Tessera, and choose Cancel. Your access continues until the end of the current billing period.

How do I restore a purchase?

If you reinstall the app or switch devices, open Tessera's settings and use Manage subscription, or reinstall while signed in to the same Apple ID. Apple restores your active subscription automatically.

How do I reset my progress?

Open the app's Me tab, then Reset progress. This clears your local learning data on the device. It cannot be undone.

What data do you collect?

None that leaves your device. Tessera has no account and no server, and uses no tracking or ads. See the Privacy Policy for the full detail.
