// TERMS

Terms of Use

Version: 2026-11-10 (release candidate period)

These terms cover your use of daana, a command-line tool for data modelling. Please read them. They are short on purpose.

1. Who we are and how you accept these terms

daana is made by Daana AB, a company registered in Sweden with organisation number 559093-5671 and its address at Torsgatan 26, 113 21 Stockholm, Sweden ("Daana", "we", "us").

Using daana requires an account, on the Free tier too. You accept these terms by ticking the checkbox when you sign up on daana.dev.

daana is intended for professional use. If you sign up or use daana for an organisation, such as your employer, you confirm that you have authority to accept these terms on its behalf. "You" then means both you and that organisation. You must be at least 18 years old.

2. Definitions

  • daana or the Software: the daana command-line tool in binary form, including the licence agent, install script and documentation we provide with it.
  • Account: your account on daana.dev, held by our licence service.
  • Licence: the signed licence lease that sets which plan and limits apply to your use.
  • Licence credentials: anything that identifies your Account or Licence to the Software, such as activation codes, tokens or leases.
  • Plan: the Free tier, the Developer trial, or any other plan we offer.
  • Your Content: your data models, YAML files, generated SQL, and any data in your databases.

3. Your licence to use daana

We give you a limited, non-exclusive, non-transferable, revocable licence to install and use daana on systems you control, for the purpose and within the limits of your Plan, while these terms apply.

daana is not open source, and its source code is not made available. We keep all rights not expressly given to you here.

You may keep copies of the daana binaries inside your own organisation, for example in an internal artifact store or in container images used only by your organisation.

Working for an organisation. An organisation may let its employees, contractors and consultants use daana on its behalf, each with their own Account, and is responsible for what they do with it. A consultant may use their own Account to evaluate daana; production work for a client runs under an Account the client is responsible for.

You must not:

  • reverse engineer, decompile or disassemble daana, except to the extent applicable law expressly allows it and that right cannot be limited by contract;
  • remove, bypass, disable or interfere with licence checks, limits or the licence agent;
  • redistribute the daana binaries outside your organisation, for example by hosting them on another site or bundling them in another product;
  • sell, rent, lease, sublicense or otherwise commercialise daana itself, or offer it to third parties as a hosted service;
  • use daana to build a competing product;
  • remove or change any copyright or licence notices.

Install daana with our install script or download the binaries from our official release page on GitHub (daana-code/daana), and check the published checksums.

4. Accounts and licence credentials

You sign up on daana.dev with an email link or "Sign in with Google". We do not use passwords.

  • One Account is for one person. Do not share an Account.
  • Keep your Licence credentials secure. Do not share them, publish them or use them on behalf of anyone else.
  • You activate a Licence with daana license activate. This shows a short code that you enter on daana.dev.
  • Tell us at support@daana.dev if you believe your Account or Licence credentials have been misused.
  • You are responsible for what happens under your Account, unless it happened because of our failure.

5. Plans, trial and limits

Free tier. You may use daana free of charge, up to the free limit (currently 90 pipelines). The current limits for each Plan are shown on daana.dev.

Developer trial. You may try the Developer plan free:

  • The trial lasts 30 days from your first activation in the CLI.
  • One trial per verified account.
  • There is no pipeline limit during the trial.
  • When the trial ends, you go back to the free limit. Your data is kept and your loads keep running; you can't deploy above the free limit until you upgrade.
  • The Developer plan is for development and evaluation, not for production use.

Fair use of trials. You must not:

  • create accounts automatically or in bulk;
  • sign up with throwaway or disposable email addresses;
  • create new accounts to get another trial or more capacity;
  • share Licence credentials.

Addresses on our reserved test domain are for Daana's own testing. We may refuse or end a trial or Account created by breaking these rules.

Emails. We send three transactional emails about your trial from an address at notify.daana.dev: when it starts, three days before it expires, and when it has expired. These are part of the service.

Paid plans. Nothing can be bought on the web during the 1.0 release candidate period. Paid plans will be offered later under separate terms or an order form. If those terms conflict with these terms, the paid terms win for the paid plan.

Plans may change. We may change the plans, their names, limits and features. We will tell you by email at least 30 days before a change that reduces what your current Plan gives you.

Support. Support on the Free tier and during a trial is best effort, with no guaranteed response time or availability.

6. Pre-release software

daana 1.0 is a release candidate from 1 December 2026, and the final 1.0.0 release is planned for January 2027. Until then, daana is pre-release software. After 1.0.0, features we mark as beta, preview or experimental are still pre-release. Pre-release software:

  • may contain bugs, including bugs that produce wrong SQL or fail to load data correctly;
  • may change in features, commands, file formats and behaviour, sometimes without backward compatibility;
  • may stop being supported when we release updates;
  • may arrive later than planned.

These terms continue to apply to 1.0.0 and later versions, with a new version date when they change.

7. Your data and your systems

daana runs on your own machines and against your own databases (PostgreSQL, BigQuery, Snowflake or DuckDB). Your data does not go to Daana.

  • You own Your Content. That includes your models, the SQL daana generates from them, and your data. We get no rights to Your Content under these terms, and we never train AI on it.
  • What connects to us. The CLI sends no usage data. It contacts the licence service only to activate and refresh your licence. Our licence service records licence events only: an event id and type, when it happened, the sign-in result, internal references to your Account and Licence, the source and region, and the licence result. These events do not include your IP address, a device or machine id, your CLI version or your email. How we handle Account and sign-up data is described in our privacy policy at https://daana.dev/privacy.
  • Your responsibility. daana creates and changes database objects and loads data. You are responsible for:
    • keeping backups of your databases and files;
    • testing models, generated SQL and deployments in a non-production environment before you use them in production;
    • checking that you have the right to process the data you use with daana;
    • the credentials, permissions and costs of your own databases and cloud accounts. Running daana on a cloud data platform can create compute or storage costs with that provider.

8. Feedback

If you send us ideas, suggestions or bug reports, we may use them freely, without paying you or crediting you. Feedback does not give us any rights to Your Content. Please do not include confidential data in feedback.

9. Acceptable use

Do not use daana to:

  • break any law or anyone else's rights;
  • access databases or systems you are not authorised to use;
  • interfere with or overload our licence service, website or sign-up flow, or try to get unauthorised access to them;
  • test our systems for security weaknesses without our written permission.

Export controls and sanctions. You must not use daana in breach of export control or sanctions laws, including those of the EU, and you confirm that you are not a person those laws prohibit us from dealing with.

10. Disclaimers and limitation of liability

Your statutory rights. Nothing in these terms limits rights you have under mandatory law, including consumer protection law where it applies to you.

Disclaimer. To the extent the law allows, daana is provided "as is" and "as available", without warranties of any kind, express or implied, including fitness for a particular purpose, accuracy of generated SQL, and uninterrupted or error-free operation. This applies especially to pre-release versions.

Limitation of liability. To the extent the law allows:

  • we are not liable for indirect or consequential loss, including lost profits, lost revenue, lost or corrupted data, cloud or database costs, or business interruption;
  • our total liability to you for all claims arising out of these terms or daana is limited to the licence fees you paid us for daana in the 12 months before the claim. Fees for consulting or other services do not count. daana is free of charge on the Free tier and during the Developer trial, so if you have paid no licence fees, you have no right to compensation from us;
  • you must make any claim in writing within two months of when you discovered, or should have discovered, what it is about.

What we do not limit. These limits do not apply to liability for death or personal injury caused by our negligence, for loss caused by our intent or gross negligence, or to any other liability that cannot be limited under applicable law.

Indemnity. If you use daana for an organisation, you will compensate Daana for third-party claims caused by your breach of section 3 (licence restrictions) or section 9 (acceptable use). This does not apply to consumers.

Events beyond our control. We are not responsible for failures or delays caused by events beyond our reasonable control, such as outages of the internet or of our providers, power failures, natural disasters, war, strikes or acts of government.

11. Suspension and termination

You may stop using daana at any time. To delete your Account, email support@daana.dev or ask in the community Slack. We then delete your Account and the personal data linked to it, as described in our privacy policy. We keep only what the law requires, and a one-way code of your email address so that we never contact you again.

We may suspend or end your Account or Licence, or refuse new Licences, if:

  • you seriously or repeatedly break these terms, including the licence restrictions, credential sharing or fair-use rules;
  • we must do so to comply with law or to protect our systems or other users;
  • we stop offering daana or a Plan. We will tell you at least 30 days before we discontinue the Free tier or the product.

Where it is reasonable, we will tell you first and give you a chance to fix the problem.

What happens on termination. If a Licence ends, daana falls back to Free tier capacity; execution is never blocked. If we close your Account because you broke these terms, your licence to use daana ends and you must stop using it. You keep Your Content, which stays on your own systems. Sections 3 (restrictions), 7, 8, 10 and 13, and any others that by their nature should continue, continue after termination.

12. Changes to these terms and notices

We may update these terms. The version date at the top shows when they last changed, and earlier versions are kept at daana.dev/terms.

For material changes, we will tell you by email at least 30 days before they take effect. Until you accept the new terms, the previous terms apply to you. If you keep using daana after those 30 days, you accept the new terms. We will also ask you to accept them the next time you sign in on daana.dev, and daana license activate will not activate a Licence until you have. Other changes take effect when published.

A notice we send to your Account's email address counts as given when we send it.

13. Governing law and disputes

These terms are governed by Swedish law, without regard to its conflict-of-law rules.

If a dispute arises, we will first try for 15 days to settle it informally. A dispute with a business user that is not settled that way is finally decided by expedited arbitration under the Rules for Expedited Arbitrations of the SCC Arbitration Institute, seated in Stockholm, in English. If you are a consumer, you keep the protection of the mandatory law of the country where you live, and you may bring a claim in the courts there.

14. Other terms

  • Whole agreement. These terms, together with our privacy policy and any order form or paid-plan terms you sign, are the whole agreement between you and us about daana.
  • Severability. If a court finds part of these terms unenforceable, the rest still applies.
  • No waiver. If we do not enforce a right straight away, we have not given it up.
  • Assignment. You may not transfer these terms without our consent. We may transfer them in connection with a merger, acquisition or sale of assets, and will tell you if we do.
