FAQ

Security & Privacy Tools FAQ

Cost, privacy, accuracy and using the tools on your phone.

Yes. The tools are free and don't need an account. Tools that run checks on our server have hourly limits so they stay fast for everyone.
Generators, encryptors and hashers run in your browser, including passwords, 2FA codes, hashes, encrypted notes, Aadhaar masking and passkeys. Checks that need to reach the internet run on our server, such as link expanding, cookie scans, website reputation, email and domain checks, SMTP tests and firewall probes. Each tool page explains what it sends.
Browser-based tools don't upload what you type. Server-side checks receive only the value they need, such as a link, domain, email address or your IP address. Some keep the result for up to a few hours so repeat checks are quick, and some pass the value to a named service such as Google Safe Browsing, VirusTotal or Have I Been Pwned. Like any website, our host also keeps standard visit logs. See our Privacy Policy for details.
It creates random passwords with your browser's cryptographic random number generator and estimates their strength. The estimate helps you choose a better password; it can't guarantee a password will never be cracked.
The Email Privacy & Data Breach Checker looks up your address on Have I Been Pwned, a public database of known breaches, and shows which breaches it appeared in. A clean result doesn't prove your address was never exposed, because not every breach is public.
No. It creates starting drafts of six website policies, with optional India DPDP, GDPR and CCPA sections, based on your answers. Check that they match how your business works, and have a qualified professional review them before publishing.
No tool can catch every threat. Results are signals to help you decide. When in doubt, don't click or pay, and check with the organisation through its official website or app.
Yes. The tools are built for phones, tablets and computers and work in modern browsers without installing anything.
