Our promise

Your material is yours.

Leonide is built from what you have already said and what you tell it. That material stays yours. Here is exactly what that means.


We are not anonymous, because building your brand means knowing who you are. What we promise is privacy. What you bring here does not leave here.


The full detail

Last updated July 13, 2026

Who this is

Leonide (“Leonide,” “I,” “we”) provides the Leonide personal-brand service. For any privacy question, contact hello@leonide.ai.

What I collect

  • Your account: your email address, and, if you sign in with Google, the basic profile Google returns.
  • Your X handle and public posts: the handle you give, and the public posts and replies I read from X to research and grade your brand. I only read what is already public.
  • What you tell me: the answers, goals, and edits you type while building and refining your brand.
  • Documents you upload: a CV or writing you choose to add, used only to understand you better.
  • Voice you dictate: if you use voice input, the short audio clip is sent for transcription and is not stored after the text comes back.
  • Usage records: basic logs of actions (for example, how many drafts you generate) to run the service, keep it secure, and understand costs.
  • Feedback: anything you send through the feedback box.

How I use it

To research, build, and keep your personal brand; to generate posts, replies, and a consistency score; to run, secure, and improve the service; and to answer you when you get in touch. That is all. I do not sell your data or use it for advertising.

Who helps process it

Leonide runs on a small set of trusted providers. They process your data only to provide their part of the service, under their own security and privacy terms:

  • Supabase — database, sign-in, and file storage.
  • Vercel — hosting and delivery of the website.
  • Anthropic — the AI that shapes your material into your brand and drafts. It does not train its models on what is sent through the API.
  • Groq — voice-to-text transcription, used only when you dictate. The audio is processed to return the text and is not used to train models.
  • X (Twitter) API — the source I read your public posts and the public conversation from.

AI training

Your material is never used to train AI models, by me or by the providers above. Your brand is built for you, not folded into anyone else's model.

Cookies

Leonide sets only the essential cookies needed to keep you signed in. There are no advertising cookies, no analytics trackers, and no third-party pixels, which is why you will not see a cookie consent banner: there is nothing non-essential to consent to.

Keeping and deleting your data

Your data is kept while your account is active. You can download your brand at any time, and you can delete your account from Settings. Deleting removes your brand, posts, comments, documents, and photo right away. Routine backups may hold copies for a short period before they cycle out.

Your rights

You can see, correct, export, or delete your data. Export and delete are built into the app; for anything else, email me. Depending on where you live, you may have additional rights under laws such as the GDPR or CCPA, and you can exercise them by getting in touch.

Security

Data is encrypted in transit, and every user's data is walled off from every other user at the database level. No system is perfectly secure, but your material is treated as private by default.

International processing

The providers above may process data on servers outside your country, including in the United States. By using Leonide you understand your data may be processed there to run the service.

Age

Leonide is not intended for anyone under 18.

Changes

If this policy changes, the date above will change with it, and a material change will be flagged where appropriate.
