Hopefully none of the emails we send you will be considered spam as within the dashboard there are four checkboxes which allow you to specify what kinds of emails we can send you (Account Related, Downtime, New Features/Changes and Promotions) and by default only one of those is ticked which is "Send me important emails related only to my account".
That tick box means we'll only send you an email if your paid plan is coming to an end or you go over your daily query allowance for five days consecutively. We also limit these query exhausted emails to one per month maximum.
On top of these emails there are some you cannot turn off for security reasons. Those include the emails we send you after you change your email address, API Key or Password. We also send you an email when you subscribe to a paid plan.
To ensure your privacy we collect only your email address to facilitate sending you an API Key and to send you important notices relating to your usage of our service. You are free to use any email address. If you do not use an API Key then we only store your IP Address so that our software can record how many queries you have made upto the allowed 100 per day. If you have an API Key we store your querying IP for a maximum of 24 hours to help us track free account abusers. We do not request or store your name, physical addresses, phone number or any other personal information.
You may want to look at our GDPR Compliance page which goes into more detail about what we store.
We record how many queries you perform with your API Key if you have one, if you do not have an API Key, we record these stats with your IP Address. We also store a list of your positive detections if you're an API key holder, this list is accessible within your dashboard. We also store for around 5 minutes the negative detections made by our API, we then run these through our machine learning engine to find more proxies to block, only proxies found this way are stored long term with the rest of the data being discarded.
If you have an API Key then the amount of queries you made over time and the positive detections you made will continue to be stored forever with that key. If you do not have an API Key and you're using the 100 free queries per day that don't need an API Key then we only store the amount of queries you made over the previous 24 hours along with your querying IP Address.
A warrant canary is a piece of information we publish before we receive any kind of warrant or court order to hand over user information. If at any time we were to receive such valid warrants or court orders we would remove the warrant canary warning you that our service is no longer safe for your data. You can view our warrant canary here: https://proxycheck.io/canary.txt
We do not share your data with anyone. Only proxycheck.io has access to your Email, API Key and Querying IP and we will keep it that way. No advertisers will be given this data, nor will we abuse your trust by sending your email spam or advertisements either from us or on the behalf of anyone else. But please note we are bound by the laws of the countries in which we operate. This is why we have a warrant canary. We will only ever give your user information out to an authority if they have a valid warrant within our jurisdiction.
When you protect your account with a password we hash it using bcrypt. This means a unique hash is stored by us and not your password itself. These hashes cannot be reversed back into your password and to further complicate attacks we supply a unique salt to your password prior to hashing. In real terms it means we follow industry best practices and your password is still safe in the event our database is breached.
