Terms of Use and Licence Agreement
Last updated: 2 November 2026
These terms apply to the Merlewatch Chrome extension and this website. They are between you and Merlewatch (an independent developer based in Victoria, Australia) (“I”, “me”, “we”). Contact: merlewatch.support@gmail.com. By installing or using Merlewatch you agree to these terms.
1. Your licence
- I give you a personal, non-exclusive, non-transferable licence to use Merlewatch.
- No resale. You may not sell, rent or charge others for access to Merlewatch.
- You may not copy, modify, reverse engineer or redistribute Merlewatch except as the law allows.
2. Price
Merlewatch is currently free. If paid features are offered later, these terms will be updated before anything can be bought.
3. What Merlewatch does, and doesn’t do
Merlewatch tells you whether a password appears in the Have I Been Pwned Pwned Passwords data set and estimates its strength. A “Not found” result means only that the password isn’t in that data set; it doesn’t mean the password is safe or secret. Strength scores are estimates.
No guarantee against hacking. Merlewatch helps you make better password choices. It can’t stop your accounts from being hacked, phished or breached, and it isn’t a replacement for unique passwords, a password manager, two-factor authentication and up-to-date software.
Merlewatch relies on third-party services (Have I Been Pwned, Google Chrome). I don’t control them and can’t promise they will always be available.
4. Your responsibilities
- Use Merlewatch lawfully and only to check your own passwords or passwords you are authorised to check.
- Don’t try to misuse, overload or attack the services Merlewatch connects to.
5. Australian Consumer Law
Our goods and services come with guarantees that cannot be excluded under the Australian Consumer Law. Nothing in these terms excludes, restricts or changes any right or remedy you have under the Australian Consumer Law (Schedule 2 to the Competition and Consumer Act 2010 (Cth)) or any other law that can’t be excluded. If Merlewatch has a major failure, you are entitled to a refund. See the Refund Policy.
6. Limitation of liability
To the extent permitted by law, and except for your rights under the Australian Consumer Law:
- Merlewatch is provided “as is”, and I give no other warranties;
- I am not liable for any indirect or consequential loss, or for loss of data, accounts, profits or opportunity, arising from your use of Merlewatch; and
- my total liability to you is limited to the amount (if any) you paid me for it.
Where the law lets me limit my liability for a failure to comply with a consumer guarantee for goods or services not of a kind ordinarily acquired for personal, domestic or household use, my liability is limited, at my choice, to supplying the services again or paying the cost of having them supplied again.
7. Updates and ending
I may update Merlewatch to fix bugs, improve security or keep up with Chrome. You can stop using Merlewatch at any time by uninstalling it. I may end your licence if you seriously breach these terms; this doesn’t affect your rights under the Australian Consumer Law.
8. Privacy
See the Privacy Policy. In short: your passwords never leave your computer.
9. Changes to these terms
I may change these terms. The date above shows the latest version. Changes won’t take away rights you already have for a purchase you’ve made.
10. Governing law
These terms are governed by the laws of Victoria, Australia. You and I submit to the non-exclusive jurisdiction of the courts of Victoria and the courts that can hear appeals from them.
