Privacy Policy for Stemwise

Stemwise: Spanish Verbs Published by OFO Labs

Last updated: 31 August 2026

The short version

Stemwise collects nothing. It has no account, no analytics, no advertising and no network code of any kind. Everything the app knows about you stays on your iPhone, and nobody, including OFO Labs, can see it.

What is stored on your device

• Your practice history: how many questions you have answered, how many you got right, your streak, and how often you have missed each class of grammar rule.
• Whether you have completed the introduction.

This is kept in the app's own storage on your iPhone. It is included in your encrypted device backup if you use one, and deleting the app deletes it.

What is not collected

Stemwise does not collect your name, your email address, your location, your contacts, your device identifiers or your usage. It contains no analytics framework, no advertising framework and no tracking of any kind. It does not show you advertisements and it never asks you to create an account.

Network

Stemwise contains no networking code. The verb list and the conjugation engine are inside the app, so it works with no connection at all.

The single exception is the purchase itself, which is handled entirely by Apple: when you buy or restore Stemwise Pro, your iPhone talks to the App Store, not to us. We never see your payment details, and Apple's own privacy policy governs that transaction.

Children

Stemwise is rated 4+ and is safe for children. It collects nothing from anyone, regardless of age.

Your rights

Because nothing leaves your device, there is nothing for us to give you, correct or delete. To remove everything Stemwise has stored, either use "Reset practice history" in Settings or delete the app.
