2. Educational Nature & Cryptographic Security Notice
Cipher Decipher provides classical cipher converters, mathematical text utilities, and educational reference articles.
Security Warning: Historical and substitution ciphers (such as Caesar, ROT13, Vigenère, Playfair, Enigma simulations, or Affine ciphers) are cryptographically obsolete and insecure. They offer zero protection against modern cryptanalysis. You agree never to use our tools to secure sensitive personal information, banking details, medical records, passwords, or classified communications.

You agree to use the Services only for lawful, educational, research, and puzzle-solving purposes. You must not:
- Use the Services for illicit data obfuscation, cyberattacks, phishing campaigns, or evasion of legal compliance obligations;
- Probe, scan, or test the vulnerability of our hosting infrastructure or attempt to circumvent security controls;
- Deploy aggressive scrapers or automated bots in a manner that degrades service latency or violates standard robots.txt directives;
- Impersonate any person, entity, or maintainer of Cipher Decipher;
- Attempt to disrupt, overload, or launch denial-of-service attacks against our web servers.
4. Client-Side Processing & User Content
Our converter tools operate within your local browser. You retain complete ownership of any text, tokens, or data you input into our tools. Because transformations happen on your device, you are solely responsible for ensuring your inputs comply with applicable laws and third-party intellectual property rights.

6. Third-Party Advertisements & Links
The Services may display third-party advertisements (such as Google AdSense) and links to external reference repositories (e.g., RFC documents, NIST publications, or Wikipedia). We do not endorse or assume liability for third-party products, services, or privacy practices. Your interactions with third-party advertisers are governed strictly by their terms and policies.
