Terms
Last updated 26 August 2026
These terms cover using Flint — the desktop app and the API behind it. Using either means you accept them. They're written to be read, not to be impenetrable.
What Flint is
A desktop agent that reads and edits files, runs commands and drives a browser on your machine, using a large language model to decide what to do. It's built on DeepSeek Harness, which is MIT licensed.
Flint is an independent project. It is not affiliated with, sponsored by or endorsed by DeepSeek. "Powered by DeepSeek Harness" is a statement of fact about the engine, nothing more.
The important one: it runs commands on your computer
Flint edits real files and executes real commands, on your machine, with your permissions. A model can misread a request and do the wrong thing. You are responsible for what you ask it to do and for the state of your machine.
Practically, that means:
- Keep your work in version control, or backed up, before letting an agent loose on it.
- Read what it proposes on anything you can't afford to lose.
- Don't point it at production systems you aren't prepared to have changed.
We aren't liable for lost work, broken builds, deleted files or anything else that follows from commands Flint runs at your direction.
Your account
- You need a working email address. One account per person.
- Your token is yours to keep secret. Anything done with it counts as done by you.
- Tell us if it leaks and we'll revoke it.
- You can stop using Flint whenever you like. Ask and we'll delete the account.
Paying for it
- Usage-based. You're charged per token at the rates published on the pricing page — the model's cost plus 25%. No subscription, no seats, no minimum.
- $0.50 of usage free each month, resetting on the 1st. Unused allowance doesn't carry over.
- The allowance is a hard cap. When it's gone, requests are refused rather than billed. You can't accidentally run up a bill you didn't agree to.
- Rates can change. Model providers change theirs, so ours follow. Changes are published here before they apply.
Fair use
Don't:
- Resell access to the API, or use your token to serve other people's traffic.
- Create multiple accounts to farm the free allowance.
- Use Flint to break the law, attack systems you don't own, or generate material that's illegal where you are.
- Try to extract our upstream provider key, or work around the metering.
We can suspend an account that does these things. If it's a mistake, email us and we'll sort it out.
What the model produces
Model output can be wrong, out of date, or confidently invented. Check anything that matters. We make no claim that generated code is correct, secure, or fit for any particular purpose, and we don't claim ownership of what you produce with Flint — that's yours, subject to the model provider's own terms.
Availability
Flint is a young product run by one person. The API may be down, slow, or changed at short notice, and features may be added or removed. There's no uptime guarantee. The desktop app keeps working with your own API key regardless of what our servers are doing — that path doesn't depend on us at all.
The engine underneath
DeepSeek Harness is MIT licensed and its copyright notice ships with the app. It is developer-preview software and introduces breaking changes; that's why engine updates are offered rather than forced. The MIT licence covers DeepSeek's code, not their name or logo.
Warranty and liability
Flint is provided as is, without warranties of any kind. To the extent the law allows, our total liability for any claim relating to Flint is limited to what you paid us for it in the three months before the claim.
Nothing here limits rights you have that can't be excluded by law.
Changes to these terms
If they change, the date at the top changes. Carrying on using Flint after that means accepting the new version.
Governing law
These terms are governed by the laws of New Zealand.
