Terms and content licence
The short version: your learning record is yours and never leaves your account. The curriculum itself belongs to Rungsy — including the parts a model wrote because you asked for them — and you keep access to all of it.
Version 2026-08-17 · last updated 17 August 2026. This is a plain-language statement of what the software does. It has not yet been reviewed by a lawyer.
- Your learning recordYours
- Progress, recall grades, review schedule, the role and goals you described when scoping a curriculum, and your graph layout. It never leaves your account.
- The curriculumRungsy’s
- Concepts, explanations, exercises and the connections between them — including the ones written because you asked for them. Rungsy pays for the generation and owns the result from the moment it exists.
- Your access to itYours
- Everything generated for you stays readable, workable and exportable for as long as you have an account, whether or not another learner ever sees it.
What is yours, and stays yours
Your progress, your recall grades, your review schedule, the roles and goals you described when scoping a curriculum, and your graph layout. None of it is shared with other learners, sold, or used to train anything. It is not attached to any content that reaches the shared library, because that content never referenced it in the first place.
You can export all of it at any time as a single JSON file, and you can delete your account, which removes every record keyed to it.
What generation costs, and who owns the output
Generating a concept calls a language model, and that call costs money. Rungsy pays for it. Your plan sets a monthly ceiling and a rate limit; both are enforced before a call is made, not after, and you can see exactly what has been spent on your account.
Because Rungsy pays for that call, the text it produces belongs to Rungsy from the moment it exists, and joins the shared library. You asked for it; you are not commissioning a work you then own. What you are buying is the curriculum, the schedule and the record of what you know — and those are exactly the things you keep.
You keep access to everything generated for your account: you can read it, work through it, and export it, for as long as the account exists.
Why it works this way
The first learner who needs a concept pays for writing it. Every learner after them pays nothing, because it is already there. That is what keeps this affordable, and it only holds if the library actually accumulates.
Under the previous terms it accumulated only as far as people opted in, which meant paying twice for the same explanation and passing that cost on. Owning what is generated is the trade that makes the second learner free, and you are usually the second learner.
Removing things
What appears on your map is your choice, and it changes what you see and nothing else.
Deleting your account removes every record keyed to it: progress, schedule, settings, and your spend history. Content generated for your account stays in the library with the link to you severed. Other learners may be part-way through curricula built on it, and material that can vanish underneath its readers is not a library. If you want a specific page taken down rather than disconnected from you, that is a different request — ask before you delete.
If something has already been written
Concepts are reused. When a curriculum is built for you, anything the library already holds is served rather than written again — faster for you and cheaper for everyone, which is the trade above seen from the other side.
Content is generated, and can be wrong
Every page in the library passes an automated gate: schema validation, the pedagogical rules the hand-written material is held to, and a real parse of every diagram. That proves a page is well-formed. It does not prove it is true.
Treat anything a person has not reviewed as what it is — a machine-written draft that cleared a structural bar.
Public pages, and search engines
Owning the content does not mean publishing all of it. Only pages a person has reviewed are offered to search engines; everything else is readable inside Rungsy and marked noindex. That gate has not changed and is not going to.
In practice nothing generated for an account is a public page today — the public library is the hand-written material. If that changes for a subject you asked for and you would rather it did not, write to the address below naming the subject, and we will record the refusal against your account. It has no effect on your own access to it.
Reporting something
Any page in the library can be reported from your account: incorrect, harmful, a copyright problem, or spam. A person reads them. An upheld report removes the page from circulation and records why.
If you do not have an account, or the matter is a copyright claim, write to legal@rungsy.com. Include the page URL and what is wrong with it.
Changes to this page
This page has a version, shown at the top. When you create an account we record which version you agreed to and when, so that what any given piece of content was generated under stays answerable rather than assumed. A substantive change gets a new version and is asked for again.
Things this page does not yet cover
It has not been reviewed by a lawyer, and two questions genuinely need one: how the terms of the model providers behind a generation interact with redistributing its output, and how an ownership term like the one above has to be presented to be binding where you live. Both are being worked on rather than waited out, and this page will say so on the date it changes.
