These terms are a contract between you and Bubblecraft AB. They are written in plain language on purpose; where a clause is legally technical, we say what it means.

1. Using the service means you accept these terms

By using the apps you agree to these terms. If you do not agree, do not use them. There is no registration and nothing to sign — the apps work without an account.

What "agree" covers, and what it does not. This is an agreement to use the apps under these terms. It is not your consent to how we handle personal data: that is set out in the Privacy Policy and rests on its own legal bases, none of which is this paragraph. The one place we ask you to choose is the cookie banner, where you separately accept or decline statistics — declining it does not stop you using the apps, and simply using the apps is not itself consent to cookies.

If you use the apps on behalf of an organization (a university, an agency, a client), you confirm that you may bind that organization to these terms.

If you are under 16 — do not use the apps. The service is not intended for children, and it is not offered to anyone who cannot agree to these terms on their own. (We do not collect date of birth and hold nothing about you on our servers, so we cannot verify this: it is a rule you keep, not one we enforce.)

2. The service, as it actually is

A browser-based writing coach. You write or paste text; the app reviews the language and suggests improvements through an AI model. It is offered free of charge, it is a work in progress, and it has no account, no subscription and no paid tier.

We may add, change or remove features at any time. We may also stop offering the apps, or a part of them, at any time. For a free service this is the honest position: we owe you the service described here, not a particular feature, and nothing here is a promise that a feature stays.

How this is funded. The service is free, and we strive to always provide a free, ad-free, privacy-by-default version to the public. To keep it that way we may accept voluntary donations, and we may later offer an optional paid tier with additional features. We do not run advertising, we do not sell or share your personal data, and we do not use your text to train models. Nothing you write is the product we sell.

3. The output is AI-generated. Verify it yourself.

This is the clause that protects you most, so it is worth reading twice.

The suggestions are produced by a language model. They can be wrong, badly phrased, confidently incorrect, or invented — including citations, references and facts that do not exist. The app is a drafting aid, not an authority.

  • You are responsible for the text you publish, submit or hand in — a thesis, a manuscript, a report, a marketing claim, a court filing, anything. Check every suggestion before you use it.
  • The apps give no professional advice: not legal, not tax, not medical, not academic. Where the text touches academic work, the rules of your institution or publisher about assisted and AI-generated writing are yours to know and follow; the app does not judge them for you.
  • Citations and references need a source you have seen yourself. The app can point at where a source belongs; it cannot confirm the source exists.
  • Where a model produces text that looks like the app has an opinion on the quality of your work — treat that as a draft to react to, not a verdict.

4. Your text

Your text is yours. We claim no ownership of what you write, and we do not publish it, license it onward, or use it to train models. Underneath that, one practical point: the app stores your text in your own browser and sends it to our AI provider when you ask for a review — the mechanics and the legal bases are in the Privacy Policy, which forms part of these terms.

Your text exists only in your browser. The app stores everything you write in your own browser's local storage — we keep no server-side backups or copies of any kind. If you clear your browser data, use private/incognito mode, switch device or browser, or the browser's storage fails, your text is gone and cannot be restored. You are solely responsible for backing up your work (for example by copying the text to a file regularly); we accept no liability for lost text or data.

What you promise us about what you send:

  • You have the right to submit it: you wrote it, or you have the necessary permission from whoever did.
  • It does not break the law, and it does not infringe anyone's copyright, trademark, confidentiality or privacy.
  • You have told anyone whose personal data appears in it what you are doing, where the law requires you to.

We never see your text unless you choose to send us feedback — and even then, only the short anonymized summary you reviewed and sent yourself, never the text itself. So these are promises, not something we screen.

5. Acceptable use

You agree not to:

  • use the apps to produce or distribute unlawful content, or material that harasses, defames or endangers others;
  • submit text you have no right to submit, or pass off AI-assisted output as work someone else did;
  • misuse the service — attacking it, overloading it, reverse-engineering it to extract the model or prompts, using another site's copy of it to resell our reviews, or scraping it;
  • imply that Bubblecraft AB endorses you, your work or your institution;
  • use the sakprosa.nu, exposi.app or sachstil.de names, logos or reviews in a way that suggests we are the author of your text.

If we get a credible complaint that you are using the apps for something clearly unlawful or to infringe someone's rights — including a notice under the EU Digital Services Act, if any of the domains ever fall under its hosting provisions — we may restrict or stop the affected use and tell you why. We have no obligation to police what you write, and no ability to in practice; we do not read your documents.

Fair use. Because the service is free, we apply a fair-use limit to how many and how often you can run a review, and we may adjust that limit over time. It exists to keep the service free and available to everyone — not to create a paywall.

6. The apps themselves are ours

The software, design, names, logos and the prompt assets behind the reviews belong to Bubblecraft AB or our licensors. You may use them as described here; you may not copy, sell, host, or build a competing service from them.

Your text never becomes ours.

7. Liability — what we answer for, and what we do not

Because the service is free, under Swedish law our liability for the free service is limited to damage caused by intent or gross negligence (simple negligence is not on us for a gratuitous service). Beyond that, and to the fullest extent the law allows:

  • The apps are provided "as they are" and "as available", without warranty of any kind — not that they are uninterrupted, error-free, accurate, or fit for your purpose.
  • We are not liable for what you do with the output: a rejected manuscript, a failed submission, a correction, a lost deadline, a penalty from an institution, a claim from a third party about your text, or the reputation of it.
  • We are not liable for indirect or consequential loss — lost income, lost profit, lost data, lost goodwill, saved-cost claims.
  • Where we are liable at all, our total liability is capped at the greater of SEK 1,000 and the amount you paid us in the twelve months before the claim. That is what a free service is worth: SEK 1,000 is the practical maximum for the tool itself, and it is deliberately more than zero, so the clause is reasonable rather than a disclaimer nobody would enforce.
  • We are not liable for the AI provider's acts, except for the provider selection and configuration we made, as described in the Privacy Policy.

What no clause here touches. These terms do not limit liability that cannot lawfully be limited: for personal injury or death caused by our negligence, for our own fraud or willful misconduct, and — where you are a consumer — our obligations under the Swedish Consumer Services Act (konsumenttjänstlagen, SFS 1985:716), the mandatory rules of the EU Unfair Terms Directive (93/13/EEC), or your rights as a data subject under the GDPR. If a clause is unfair or void, that clause falls away and the rest stands.

We never exclude or limit your GDPR rights in these terms. The Privacy Policy prevails on anything about your personal data.

8. Changing these terms

We can and will change these terms as the product changes. The way we do it is deliberately constrained, because a free-for-all change clause is void against consumers and would leave us with nothing enforceable.

  • We will give notice before a change applies: at least 30 days, shown in the app (a banner or a notice on the start screen) and dated in the "Last updated" line above.
  • For changes you could reasonably be expected to object to — a new restriction on your use, a new category of personal-data processing, a change to liability — the notice will say what changed and will offer a way to stop using the apps before the change takes effect. Not using the apps any further is how you decline.
  • Continued use after the notice period means you accept the change.
  • We may change the terms without notice only when we have to: to comply with law or an authority's order, to close a security hole, or to reflect a factual change that does not affect your rights (a corrected address, a feature that no longer exists). Clarifications of wording that change no meaning also apply immediately.
  • The version that applied to your use at any time is the dated one above. If you need an old copy, ask at info@bubblecraft.se and we will provide it.

9. Ending your use

There is no account to close. Stop using the apps, or clear the site's data in your browser, and that is it. We may stop serving the apps to you — for example if you break §5, or if we shut the service down — and we will say why where we reasonably can. Sections 3, 4, 6, 7 and 10 continue to apply after your use ends.

10. Governing law and disputes

Swedish law applies, excluding its conflict-of-law rules, and Falu tingsrätt (Falu District Court), Sweden is our agreed venue.

Two honest limits, so you are not surprised: if you are a consumer living in the EU/EEA, you may still bring a claim in the courts of your own country — Brussels I Recast gives you that and we cannot take it away — and mandatory consumer protection law in your country of residence may apply to you in addition to, or instead of, Swedish law. For a free tool, we consider it fair that it stays that way.

If anything in these terms is decided to be invalid, the rest remains in force, and we will replace the invalid clause with the closest valid wording that has the same effect.

11. Contact

Questions about these terms: info@bubblecraft.se
Privacy, data-protection requests and complaints about how we handle data: privacy@bubblecraft.se

For disputes with a company, general consumer advice in Sweden is available from Allmänna reklamationsnämnden (ARN) and Konsumentverket — even for a free service, they are the natural first step before court.

These terms work together with

  • Privacy Policy — what we do with personal data, your rights, the AI provider, hosting, statistics.
  • Cookie Policy — the cookie banner and what is measured.

Where these terms and the privacy policy disagree about personal data, the privacy policy governs.
