This policy explains what Gadlus LLC ("Letronna", "we") collects when you use letronna.ai, the Letronna app and command-line tool, and our hosted models, and what we do with it.
What we collect
- Account details: your name and email address, and the sign-in method you choose (such as GitHub or Google). Sign-in is handled by our provider Clerk.
- Devices: for each computer you sign in on, a label and the approximate country and city it was last used from, so you can recognise and sign out devices.
- Usage: for hosted models, the model used, how much each request used (tokens, or the number of images, characters of speech, or seconds of audio or video) and its cost, so we can charge credit and show your usage.
- Billing: your plan, credit balance, the IDs our payment providers give your customer record and subscription, and a record of your payments. Your card details go to those providers, not to us.
- Wallets: if you create a LETRO wallet, its address. The keys are held by our wallet provider Privy, not by us.
- Partnership inquiries: if you send one from letronna.ai/partner, what you write in it (your name, email address, company, link, role, the accounts you give and your proposal), the country your request came from, the language of the page and the site that sent you to it. Your IP address is kept only as a code that changes every day, to limit abuse of the form. We use them to answer you and to consider a partnership, and delete them when you ask.
- Site visits, only if you allow it: the pages you view on letronna.ai (their address without the query string, and their title), the page that sent you, your browser, operating system, device type, screen size and language, and the country, region and city worked out from your IP address. They are counted by Umami, an analytics tool that runs on our own servers. It sets no cookies and does not store your IP address; it groups the pages of a visit under an identifier that changes every month, so it cannot recognise you from one month to the next or follow you to other sites.
What we do not collect
We do not store the prompts you send to hosted models or the answers that come back beyond what is needed to deliver them, and we do not use them to train models. Chats you have in the app and the command-line tool are stored on your own computer.
Why we use it
To run your account, deliver hosted models, charge and show your credit, prevent abuse, keep the Service secure, and contact you about your account. If you allow it, we also count site visits to learn which pages people read and improve the site. We do not sell your personal information.
Who we share it with
Only the providers that run the Service for us, each for its part: Clerk (sign-in), Stripe and its Link service (payments, and the merchant of record for most purchases), Paddle (payments, as the merchant of record for subscriptions started through it), Privy (wallets), our hosting and network providers, and the AI model providers that process your requests. Requests to model providers identify you only by an internal account number, never your name or email. Site visit counts stay on our own servers and are not shared with anyone. We may also share information if the law requires it.
How long we keep it
Account, device and usage records are kept while your account is open. Payment records are kept as long as tax and accounting rules require. When you close your account we delete or anonymise the rest. Site visit counts hold no name, email or IP address and are kept as long as they help us improve the site.
Your choices and rights
You can see and change your account details in your dashboard, sign out devices, and ask us for a copy of your data or to delete it by writing to support@letronna.ai. Depending on where you live you may have further rights, such as to object to processing or to complain to a data protection authority.
Cookies and analytics
We use the cookies needed to keep you signed in, set by our sign-in provider Clerk, and keep a few settings in your browser's local storage, such as your choice of language and your answer about analytics. We do not use advertising or tracking cookies.
Site visits are counted only if you allow it. A banner asks once; your answer is kept in your browser, and you can change it at any time with the button below or the Cookie settings link in the site footer. If your browser sends a Global Privacy Control signal, we take it as a no and do not ask.
Changes and contact
If we change this policy we will update the date above and, for significant changes, tell you. Questions: support@letronna.ai.
