MyDefense

A growing security toolbox · free

Check it before it costs you.

MyDefense is a set of independent tools for the things that go wrong online: a link you do not trust, a password that may have leaked, a photo that shows where you live, a website that protects nothing. Use them free, with no account. A free account adds saved reports, email analysis, erasure requests and the Academy, and every new tool lands in the same place.

What happens to what you enter

Some checks never leave your device

3 of the free tools run entirely in your browser, so what you type or pick is never sent to us. The others run on our servers, because someone has to open the link or fetch the website.

One tool among the others · data erasure requests

Anyone may require a company to erase or destroy the personal data it holds about them, and to pass that instruction on to everyone it shared the data with.

Your right to erasure: KVKK Art. 11 · GDPR Art. 17 · CCPA §1798.105

For data held by a company you never dealt with, removal is not a button, it is a right. With a free account we prepare the request under the law that applies where you live, send it, and keep every letter and reply in one place.

It is a legal request, not a guarantee: the company has a statutory deadline to answer, and we keep track of it for you.

Plans

Everything is free.

Every tool here is free while we grow, and so is the account. Later, some services may be paid, through a plan or a wallet you top up and spend per use. If a service is going to change, we tell you in the app and by email first, and the pricing page always shows what is planned.

Questions

Asked before signing up

→Do I need an account?
Not for the free tools: the message checker, link checker, password check, photo cleaner, website checks and the rest work without one. A free account saves your detailed reports as PDFs and adds email analysis, a deeper scan of your own domains, erasure requests, canary tokens, a registered-sites search and the Academy.
→Is it really free?
Yes, for everyone. In the future some services may be paid, through a plan or a wallet you top up. Before any service changes we tell you in the app and by email, and the pricing page shows what is planned for each.
→Do you ever see my passwords?
No. The password check runs in your browser: the password itself never leaves your device. The same goes for the photo cleaner and Paste Guard, which work on your device and send nothing to us.
→How do the erasure requests work?
You pick the company that holds your data and we prepare the request under the law that applies to you, then send it and track the answer. In Türkiye that is KVKK Article 11, in the EU and UK GDPR Article 17, in California the CCPA, and a courtesy request elsewhere. A request is not a guarantee of erasure; the company must answer within its legal deadline.
→Can you scan or clean my Instagram, Facebook or YouTube account?
Not right now. Connecting social accounts is paused while we finish the approvals each platform requires, and it returns when they are granted. Every tool on this page works without such a connection.
→Is dark web monitoring switched on?
Not yet. Continuous monitoring depends on a breach-data subscription we have not started, so it is marked Coming soon on the pricing page. Meanwhile the password check tells you whether a password has appeared in a known breach, and you can look up an address on haveibeenpwned.com.
