FAQ

All of your frequently asked questions answered.

Where and how are my encryption keys stored?

The public / private keypair is stored within our database server in Switzerland, there are two asymmetric keys, master and encryption. The master key is used to encrypt your encryption key while the encryption key is used to encrypt any data you have. We do not have access to either of them as your passphrase is required to decrypt. You can retreive them by downloading your data in the dashboard.

How can I be sure my data is safe, aren't you using proprietary code?

You're right, nothing and nobody can be trusted, however we have made our best efforts be as transparent as possible and have therefore released our user encryption module source code on GitHub, you can access it by clicking the icon in the footer. The general rule is that you shouldn't provide any information you wouldn't want to be leaked.

Is my data safe / encrypted in transit?

No, while we make sure to encrypt any data stored on our servers / infrastructure, data is not being encrypted as soon as it exits our systems onto the GSM / CMDA network.

What can I use this service for then?

Anything you want really, if you need to create a second account on Signal, Telegram, Whatsapp or any other service that requires a mobile phone number. You can even use it with social networks to stop them selling your data to advertisers. You can use it to message friends or relatives if you need to.

What countries can I send/receive messages to/from?

You can receive and send messages from any country available in our helpful message pricing box. Basic rule is that most countries will work perfectly fine, on some sent messages however your number may be replaced with a "SMS" contact, in those cases we include your number at the end of the message.

Do you offer a trial, something I can test?

Not officially for obvious reasons, however you can test the system by messaging our public number available on the homepage.

Are any messages blocked?

Nope, as far as we are aware no incoming/outgoing messages are blocked and no filtering is taking place.

What happens if Crypton.sh were to be compromised?

Most of the information we store is encrypted with your private key, only some metadata (such as dates) remains unencrypted. We do recommend you use an email that cannot be traced back to you.

What happens if Crypton.sh receives a search warrant / gag order?

We will comply with any lawful search warrant, however due to our security practice our canary, which you can find in the footer, will not get updated.

Can you read any of my outgoing/incoming messages?

Nope, even if we wanted to, we could not, we only know when they arrive but not much else.

What are the rules regarding usage?

Please do not use Crypton.sh for evil things (or harm anybody for that matter), we would appreciate not having police coming over.

What countries are numbers available in?

At the moment we only offer phone numbers from the United Kingdom, but we are working on providing more countries.

Can I use this service over TOR?

Yes, our service is available over TOR, you can find the link in the footer.

Do you recycle phone numbers?

We try to recycle phone numbers when used, sometimes however this doesn't happen and we cannot guarantee it, we will of course exchange your number if it does not work free of charge.

What happens when my number expires?

Your number is put into a grace mode for one week where you will be sent and email every day, as long as you don't select it for removal and have enough top-up available, your number will renew automatically.
