Tools are for general use
Bluebird's calculators, converters, generators, editors, and utilities are provided for convenience and information. Outputs may contain errors, rounding differences, library-specific quirks, or edge cases we haven't seen yet.
Not professional advice
Nothing on Bluebird is legal, medical, financial, tax, engineering, or safety advice. In particular:
- Health / body calculators (BMI, calorie, body-fat) are estimates. Talk to a qualified professional before making health decisions.
- Financial calculators (loan, compound interest, discount) are simplified models. Consult a licensed advisor before major financial decisions.
- Cryptography tools (AES, hash, passphrase, QR) are for learning and convenience. Do not rely on them for high-stakes security without an independent audit.
- PDF redaction, metadata, and X-ray tools help you find and remove sensitive content, but no automated tool can guarantee complete redaction. Manually review before publishing.
- Legal-adjacent tools (NDA drafts, contract clauses, etc.) are templates, not legal advice.
Always verify outputs
Before relying on any output for a real decision, verify it independently — with a second tool, a professional, or manual review. The bigger the consequence, the more you should verify.
Third-party libraries
Many tools use open-source libraries (pdf.js, ffmpeg.wasm, browser-image-compression, pdf-lib, and others). Their limitations and bugs are outside our control. We update them when meaningful improvements ship.
No warranty
As stated in our Terms of Service, everything is provided "AS IS" without warranty of any kind. Use at your own risk.
