Disclaimer

The tools and guides on this site are provided for learning, development and everyday reference. Please read the following before relying on them:

1. Results are for reference

Encoding and decoding, hashing, encryption, formatting, base and time conversion all follow published standard algorithms, but we cannot guarantee correctness for every input and environment. Verify results yourself before using them in important work, and keep the original data and backups.

2. Security tools are not a security guarantee

The encryption, hashing, password generation and file verification tools are computational aids only. Security depends on key strength, how you use it and the surrounding environment; these tools cannot guarantee your data will not be intercepted or altered elsewhere (device, transport, storage). Never treat this site as your only safeguard.

3. Local processing and your responsibility

Most tools compute locally in the browser and never upload your input. That also means unsaved results are lost when you refresh or close the page, and we cannot recover them — copy or download what you need.

4. Guides age

Articles and documentation reflect the technology and practice at the time of writing and may become partly outdated (algorithm recommendations, command changes, service policies). For critical decisions rely on official documentation and current specifications — and tell us if we have missed something.

5. External services and links

Some features depend on third-party APIs (such as IP geolocation). Their availability and accuracy are controlled by those providers and may change or break without notice. We make no guarantees about third-party sites or services.

6. Advertising disclosure

The site is funded by advertising served through Google AdSense. Ads are delivered and measured by Google and its partners and do not represent our views or endorsement.

7. Contact

If anything above is unclear, contact us atcontact@yyago.top. The site is run by an individual with limited time, and we appreciate your understanding.
