How can we help?
Find quick answers for purchases, AI tools, local study data, and question reports. If something still is not right, email us with your device and app version.
Purchases
Purchases are processed by Apple or Google. If a completed purchase is not recognized, open Settings → Access → Restore purchases while signed in to the same store account. A pending payment will not unlock access until the store confirms it.
OpenRouter and AI tools
The AI tools require your own OpenRouter API key and an internet connection. The key is stored in the platform’s protected local credential storage. You can remove it from Settings at any time. Provider availability, limits, and charges are controlled by OpenRouter and the selected model provider.
Resetting study data
Settings contains separate controls for resetting preferences and deleting learning results. Deleting results removes completed attempts, saved mistakes, answer history, study time, and the unfinished test from that device.
Before reporting a question
Include the section, test number, question text, selected language, and what appears incorrect. Do not send passwords, API keys, payment details, driver-license numbers, or other sensitive information.
