Terms of Use

Effective October 30, 2026

The short version

  • Cluo is free to use for fun and practice.
  • Puzzles are generated automatically; if a clue seems off, tell us and we'll fix it.
  • Cluo is provided “as is”.

These terms are an agreement between you and Auvler Systems, based in Ontario, California (“we”, “us”), for the use of the Cluo app and the Cluo pages on auvler.com (the “Service”). By using Cluo, you agree to these terms and to our Privacy Policy. If you don't agree, please don't use Cluo.

1. Using Cluo

We give you a personal, non-exclusive, non-transferable license to use Cluo on devices you own or control. You may not sell, rent or redistribute the app or its puzzles and word lists, or use it to break the law.

2. Puzzles and clues

Crosswords and sudokus are generated by the app from our own word lists and clues. We review them, but a clue may occasionally be unclear or have more than one fitting answer. If you find one, write to us and we'll correct it in an update.

3. Our rights

The Cluo app, name, icon, design, word lists and clues belong to Auvler Systems. These terms don't give you any rights to them other than the license to use the app.

4. Changes to the Service

We may change, add or remove features, or stop offering Cluo. Because the app works on your device, the version you have will usually keep working.

5. Disclaimers

Cluo is provided “as is” and “as available”, without warranties of any kind, to the extent allowed by law. We don't promise it will be error-free or always available.

6. Limitation of liability

To the extent allowed by law, Auvler Systems won't be liable for indirect, incidental, special, consequential or punitive damages, or for loss of data, profits or opportunities, arising from your use of Cluo. Our total liability for any claim related to Cluo is limited to the greater of the amount you paid us for Cluo in the 12 months before the claim, or $50. Some places don't allow these limits, so they may not apply to you.

7. Disputes and governing law

These terms are governed by the laws of the State of California, without regard to its conflict-of-law rules. Before filing a claim, please contact us at [email protected] so we can try to resolve it informally. Any dispute that can't be resolved this way will be handled in the state or federal courts located in San Bernardino County, California, unless the law where you live gives you the right to bring it elsewhere.

8. App stores

If you got Cluo from the Apple App Store or Google Play, that store's terms also apply to the download. These terms are between you and Auvler Systems, not Apple or Google. Apple and Google are not responsible for Cluo or its support, maintenance, or any claims about it; we are. Apple and its subsidiaries are third-party beneficiaries of these terms and may enforce them against you.

9. Changes to these terms

We may update these terms. We'll change the date at the top. If you keep using Cluo afterward, you accept the new terms.
