Credits do not have an expiration time and depend on your usage; their duration is determined by your activity level. Typically, a question consumes approximately 0.3 credits. For instance, if you ask 3 questions per day, it will total around 30 credits per month. Initially, each user receives a free 50-credit. With normal usage patterns, it takes months before credits are run out. Also, we don't charge for entering new notes; credits are only spend during inference processes. With credit-based usage, you aren't required to pay when inactive, no commitment. The system is cost-effective in terms of usage duration. We operate on a nearly non-profit basis :)

None of your notes are stored on our server; they remain locally stored on your phone. We exclusively offer Apple sign-in to ensure users can conceal their email addresses, maintaining complete anonymity towards our server. However, for inference purposes, some data is transmitted to OpenAI or other language model providers(we will soon offer users the choice between our open-source model and commercial model options). There is no viable method to run a suitable language model on a mobile device; while there have been attempts, none have met the quality standards required for inference. We are actively exploring options to facilitate inference directly on the phone, and we hope to offer this functionality soon. Lastly, we get your positive vibes, we will update our website as well :)

Thanks for your feedback, we really appreciate it.
