What you are agreeing to
By downloading, building or running LEDAR, you accept these terms and the licence they point at. If you do not accept them, do not run the software.
There is no account to create and no service to sign up for. LEDAR runs on your computer, and LEDAR operates no server that your copy connects to.
What the software does
- It connects to a PostgreSQL database you choose and reads from it.
- It never writes to that database. The most it will ever do is print SQL for you to run yourself.
- It refuses to scan through a role the database reports as a superuser, and provides no way to override that refusal.
- It stores its results on your own machine and sends them nowhere.
These are design commitments enforced in the code, and they are the reason the product exists in this shape. They are not, and cannot be, a promise that no defect will ever exist. See the warranty section below.
Your responsibilities
- You must be entitled to connect to the database you point LEDAR at. Access you do not have permission for is not made lawful by the tool being read-only.
- Give it a role that cannot write. LEDAR refuses superuser roles, but the guarantee you actually want comes from the database, not from the application — see creating a read-only role.
- A long-running read can still hold a lock and slow a busy system. LEDAR sets statement, lock and idle timeouts to limit this, but scheduling remains your call.
- If you configure an AI provider, you are responsible for your relationship with that provider, including their terms, their pricing and their handling of what you send.
AI output
LEDAR writes its own sentences and runs its own queries; the model chooses which part of your schema a question is about, from a menu the product built. The full description is on How LEDAR uses AI.
An answer is not advice, and it is not a warranty about your system.
The product states what it did not look at and what it could not determine. Those statements are part of the answer, not caveats attached to it, and an answer read without them is being read wrong. Decisions with financial, legal, medical or safety consequences need verification against the database itself.
No warranty
The software is provided "as is", without warranty of any kind, express or implied, including but not limited to the warranties of merchantability, fitness for a particular purpose and non-infringement.
This is the standard disclaimer, and here it is meant plainly: this is pre-1.0 software. Its own status page lists measurements that came out badly, including prompt-injection attempts that succeeded. Read that page before you rely on an answer.
Limitation of liability
To the maximum extent permitted by applicable law, the author is not liable for any indirect, incidental, special, consequential or exemplary damages, or for any loss of profits, revenue, data or goodwill, arising out of or in connection with the software or these terms, whether in contract, tort or otherwise, and whether or not the possibility of such damage was advised.
Nothing in these terms excludes or limits liability that cannot lawfully be excluded or limited, including liability for death or personal injury caused by negligence, or for fraud.

Changes
These terms may change as the product does. The effective date at the top changes with them, and the published history of the source repository records when. Continuing to use the software after a change means accepting the changed terms.
