Protect Your Privacy Today
Our tools help you understand the privacy practices of email providers before you share your personal information. Pair them with Temp Postal's temporary email for complete protection.
Why these tools exist
Most people only discover an address is compromised when the spam starts. The breach checker closes that gap: it tells you whether the address has surfaced in a known dataset so you can rotate passwords on the affected services and stop reusing that address for new signups. If the answer is yes, the practical response is a password manager, unique passwords, and a disposable address for anything low-trust from that point on.
The privacy checker looks at the other half of the problem - how much your address itself gives away. A firstname.lastname address on a corporate domain identifies you, your employer and often your role before you have typed anything else. It scores the address on that exposure and suggests the pattern that would leak less.
How to use them together
Run the breach check on your primary address first. Anything that comes back positive should get a fresh password and, where the service supports it, two-factor authentication. Then run the privacy check to see how identifying that address is when you hand it out. Between the two you get a clear split: the accounts worth protecting with a permanent address, and the long tail that should have been disposable all along.
From there, use a temp address for the long tail. Downloads, coupon walls, forum accounts, trials and one-off signups do not need your real address, and every one you avoid is one fewer place your primary can leak from in the next breach.
Frequently asked questions
Do these tools store the email address I enter?
No. The address is used to run the check and is not retained afterwards, not profiled, and not shared. There is no account to create and nothing to delete later.
Is the breach checker accurate?
It reflects publicly known breach datasets. A negative result means the address has not appeared in those datasets - it cannot prove an address was never exposed in a breach that has not been disclosed or indexed.
What should I do if my address shows up in a breach?
Change the password on the affected service and anywhere you reused it, turn on two-factor authentication, and stop using that address for new low-trust signups. Use a disposable address for those instead.
What does the privacy checker actually measure?
How much the address itself reveals: whether it contains your real name, whether the domain identifies your employer or school, and whether the pattern is guessable from public information about you.
Are the tools free?
Yes, both are free and require no account. Paid plans cover inbox features - longer retention, custom domains and API access - not these checkers.

Quick answer
What free privacy tools does Temp Postal offer?
- No account, no signup and no logging of the addresses you check.
- Breach checker reports known public exposure for an address.
- Privacy checker scores how much an address reveals and how it is likely to be used.
- Each tool links to the practical step that fixes what it found.
Why we publish diagnostics rather than dashboards
Most privacy tooling asks you to hand over the very data you are trying to protect and then charges for a monitoring subscription. Our tools answer a single question and stop. That keeps the privacy story simple: there is nothing to leak because nothing is retained.
It also makes the tools genuinely useful in the middle of a task. If you are deciding whether to hand an address to a service, a ten second answer changes the decision. A dashboard you have to sign up for does not.
The breach checker
The breach checker tells you whether an address appears in publicly known breach corpora and what categories of data were exposed. A hit does not mean an account is currently compromised, but it does mean the address is in circulation among people who buy such lists, which is the practical reason for the spam that follows.
The useful response to a hit is rarely to change the password and stop. It is to stop using that address as the universal identifier, which is exactly what a disposable address for every low-trust signup achieves.
The privacy checker
The privacy checker scores an address on how much it reveals: whether it encodes your real name, whether the domain identifies your employer, whether the local part is guessable, and whether the address is likely already enrolled in marketing databases.
Most personal addresses score badly, which is the point. An address built from your real name at a major provider is a permanent identifier that follows you between unrelated services and lets data brokers join records that would otherwise stay separate.
What the tools deliberately do not do
They do not monitor continuously, email you alerts, or store the address you typed. There is no account, so there is no profile accumulating behind the scenes.
They also do not claim to know about breaches that have not been made public. No tool can, and any service implying otherwise is selling confidence rather than information.
Frequently asked questions
Are the tools really free?
Yes, with no account and no usage limit for normal use. They exist because they are useful, not as a trial for something paid.
Do you store the address I check?
No. The check happens and the address is discarded. Nothing is written to a profile because there is no profile.
How current is the breach data?
It reflects publicly disclosed breach corpora, which lag the incidents themselves. A clean result means no known public exposure, not a guarantee of safety.
What should I do if my address shows up in a breach?
Change the password on any account sharing it, enable two factor authentication where offered, and stop reusing that address for new low-trust signups.
Is there an API for these tools?
The tools themselves are browser only. The mail platform has a documented API, covered on the developer pages.
