Hopefully none of the emails we send you will be considered spam but to keep you in complete control we have provided five email preferences within the customer dashboard which allow you to specify the kinds of emails we can send you (Account related, Query overage notices, Upcoming payment notices, Downtime and New Features/Changes) and by default only one of those is ticked which is "Important emails related only to my account".
That setting toggle 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 limit those 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 two-factor settings, email address, API Key or Password. We also send you an email when you subscribe to a paid plan.
We do store a few cookies when you visit our website, we limit them only to what is necessary and we've detailed them below.
And that is all the cookies. Just those six kinds of cookies are the ones you can expect. We do not run any kind of external marketing or social media cookies. We don't embed third party analytical services, just our own self-hosted Matomo. If you have any questions about our cookies please feel free to contact us.
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. If you purchase a paid subscription we ask for your name and address but those are only stored with Stripe (our payment processor) and are not stored on our own servers.
You may want to look at our GDPR Compliance page which goes into more detail about what we store and where we store it.
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 number of queries you made will be stored forever. In addition to that the positive detections you made will be stored for 12 months and then deleted. 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.
You can request via our support page to have all the information we hold about you deleted, we try to fulfil all of these requests within 24 hours.
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
Apart from these two relationships we don't share your information with any other entity.
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.
