Where is data stored? Is it secure?

All data is stored locally on your computer using SQLite database — no internet required for basic use. AI analysis features require network access to call language models, but your family data is never uploaded to any server. You can export and backup your data at any time.

Which operating systems are supported?

Currently supports Windows. Other systems are planned — stay tuned.

Does AI analysis require extra payment?

AI features require you to configure your own model API. You can also use a local Ollama service, or free APIs like Zhipu, DeepSeek, or Tongyi Qianwen.

How many family members can I add?

Unlimited families, unlimited members.

Will my data be lost after the trial ends?

No! All data you entered during the trial is fully preserved. After purchasing a license, all features are immediately restored — no need to re-enter data.
