Roy's Tools

> No clutter, no ads, no bait-n-switch—just simple tools that work at no cost

Terms of use

By using Roy's Tools, you agree to these terms. If you disagree, do not use the site.

No warranties

Tools are provided as-is. Aviation, weather, DNS, financial, calculator, and legal-adjacent data can be incomplete or delayed. Verify critical information with authoritative sources. BMI, ovulation, and pregnancy calculators are arithmetic helpers, not medical advice.

Acceptable use

Do not use the utilities to violate law, platform terms, or intellectual property rights. Video and download helpers are only for content you may lawfully access. Do not attempt to probe, overload, or misuse APIs exposed through the UI.

Third parties

The site may link to or rely on third-party services (for example Open-Meteo, ECB/Frankfurter rates, ADS-B hosts, Twilio, Sightengine). Those services have their own terms and privacy policies. AI-image pixel scores, C2PA labels, and the local watermark scan are not guarantees of authenticity. Invisible-watermark stripping is for files you may lawfully process; do not use it to misrepresent AI-generated content as human-made.

BYO credentials

Features that accept your own API keys (for example Twilio) run under your responsibility. You must safeguard keys and comply with the vendor's rules.

Direct answer

Roy's Tools is provided as-is. You may use it only for lawful purposes. Flight, weather, DNS, currency, and calculator figures are not operational, medical, tax, or lending advice. Video downloads are only for content you may lawfully save.

How to use this page

  1. Use the tools as helpers. Confirm aviation, weather, medical, tax, and financial decisions with the authority that owns that decision.
  2. Respect copyright. The video helper accepts only allowlisted public URLs, and only when you may lawfully access and save that video.
  3. Own your API keys. Twilio and similar bring-your-own credentials stay your responsibility, including the vendor’s rules.

Sources

  • Third-party services — Open-Meteo, ECB reference rates via Frankfurter, ADS-B hosts, adsbdb, Twilio, and Sightengine have their own terms.

Limits

  • A C2PA label, a local watermark scan, or a Sightengine score is not a guarantee of authenticity.
  • Watermark stripping is for files you may lawfully process. It does not make an AI image into a photograph.
  • BMI, ovulation, and pregnancy calculators are calendar and arithmetic helpers, not medical advice.

Can I download any video I find?

No. The video helper is only for content you may lawfully access and save. Respect copyright, platform terms, and local law.

Are flight, weather, or FX figures guaranteed?

No. Tools are provided as-is. Confirm operational, medical, tax, or financial decisions with authoritative sources.
