Psiphon is committed to protecting the privacy interests of its customers, end users, distributors and suppliers. This privacy policy is intended to provide you with general information on how your personal information may be used. Psiphon is a Canadian corporation with its head office located in Ontario, and our privacy policy has been developed to reflect Canadian and Ontario privacy laws and statutes.
For further information regarding Canadian and Ontario privacy laws, please visit:
From time to time, Psiphon will add entries to our Privacy Bulletin. This will happen for two reasons:
When using a VPN or proxy you should be concerned about what the VPN provider can see in your data, collect from it, and do to it.
When you use a VPN, all data to and from your device goes through it. If you visit a website that uses unencrypted HTTP, all of that site's data is visible to the VPN. If you visit a website that uses encrypted HTTPS, the site content is encrypted, but some information about the site might be visible to the VPN. Other apps and services on your device will also transfer data that is encrypted or unencrypted. (Note that this is distinct from the encryption that all VPNs provide. Here we're only concerned with data that is or is not encrypted inside the VPN tunnel.)
For unencrypted services, it is possible for a VPN provider to see, collect, and modify (e.g., injecting ads into) the contents of your data. For encrypted data, it is still possible for a VPN to collect metadata about sites visited or actions taken. You should also be concerned with your VPN provider sharing your data with third parties.
We DO NOT collect or store any VPN data that is not mentioned here.
We DO NOT modify the contents of your VPN data.
We DO NOT share any sensitive or user-specific data with third parties.
We will define some categories of data to help us talk about them in the context of Psiphon.
While a user's device is tunneled through Psiphon, we collect some information about how they're using it. We record what protocol Psiphon used to connect, how long the device was connected, how many bytes were transferred during the session, and what city, country, and ISP the connection came from. For some domains (but very few, and only popular ones) or server IP addresses (e.g., known malware servers) that are visited, we also record how many bytes were transferred to it. (But never full URLs or anything more sensitive. And only domains of general interest, not all domains.)
Geographical location and ISP info are derived from user IP addresses, which are then immediately discarded.
An example of user activity data might be: At a certain time a user connected from New York City, using Comcast, and transferred 100MB from youtube.com and 300MB in total.
We consider user activity data the most sensitive category of data. We never, ever share this data with third parties. We keep user activity data for at most 90 days, and then we aggregate it and delete it. Backups of that data are kept for a reasonable amount of time.
Data is “aggregated” by taking a lot of sensitive user activity data and combining it together to form coarse statistical data that is no longer specific to a user. After aggregation, the user activity data is deleted.
An example of aggregated data might be: On a particular day, 250 people connected from New York City using Comcast, and transferred 200GB from youtube.com and 500GB in total.
Aggregated data is much less sensitive than activity data, but we still treat it as potentially sensitive and do not share it in this form.
When sharing aggregated data with third parties, we make sure that the data could not be combined with other sources to reveal user identities. For example, we do not share data for countries that only have a few Psiphon users in a day. We make sure that the data is anonymized.
We also never share domain-related information with third parties.
An example of shareable aggregated data might be: On a particular day, 500 people connected from New York City and transferred 800GB in total.
An example of data that is not shareable: On a particular day, 2 people connected from Los Angeles. Those people will be included in the stats for the entire US, but that is too few people to anonymously share city data for.
Activity and aggregated statistical data are vital for us to make Psiphon work best. It allows us to do things like:
Shareable aggregated data is shared with sponsors, organizations we collaborate with, and civil society researchers. The data can be used to show such things as:
Again, only anonymized shareable aggregated data is ever shared with third parties.
We sometimes use advertisements to support our service, which may use technology such as cookies and web beacons. Our advertising partners' use of cookies enable them and their partners to serve ads based on your usage data. Any information collected through this process is handled under the terms of our advertising partners' privacy policies:
We use Google Analytics on some of our websites to collect information about usage. The information collected by Google Analytics will only be used for statistical analysis related to your browsing behaviour on this specific site. The information we obtain from Google Analytics is not personally identifying, nor is it combined with information from other sources to create personally identifying information.
Google Analytics sets a permanent cookie in your web browser to identify you as a unique user the next time you visit the site, but this cookie cannot be used by anyone except Google, and the data collected cannot be altered or retrieved by services from other domains.
Google’s ability to use and share information collected by Google Analytics about your visits to this site is restricted by the Google Analytics Terms of Use and the Google Privacy Policy. You may choose to opt out by turning off cookies in the preferences settings in your web browser.
We use Amazon S3 to store assets such as website files and Psiphon server discovery lists. We sometimes enable logging of downloads of these files. Analyzing these logs helps us to answer questions like "how many users are starting but not completing the download of the server discovery list?", "how is the downloaded data split between website assets and server discovery?", and "is an attacker making a denial-of-service attempt against our websites?"
S3 bucket access logs contain IP addresses, user agents, and timestamps. These logs are stored in S3 itself, so Amazon has access to these logs. (However, Amazon already serves the files, so they can already access this information.) Psiphon developers will download the logs, aggregate and analyze the data, and then delete the logs. Raw data will be kept only long enough to aggregate it and will not be shared with third parties.
The PsiCash system only collects information necessary for the functioning of the system, monitoring the health of the system, and ensuring the security of the system.
The PsiCash server stores per-user information to allow for operation of the system, including:
Creating a PsiCash account is optional. If an account is created, account-specific information such as username, password, and email address (if provided) are stored on the server. When logged in to a Psiphon client, the username is also stored locally.
In the user's web browser, some data is stored to allow for earning rewards and making purchases. This data includes:
For monitoring system health and security, system activity data is collected and aggregated. This data includes:
Individual user data is never shared with third parties. Coarse aggregate statistics may be shared, but never in a form that can possibly identify users.
PsiCash server resources are stored in AWS, which means Amazon has access to the data.
Users create and manage their PsiCash accounts on the my.psi.cash website.
my.psi.cash uses Google’s reCAPTCHA v3 (hereinafter “reCAPTCHA”), which protects websites from spam and abuse by non-human users (i.e., bots). reCAPTCHA collects personal information that is required for the functioning of the technology and is subject to its own privacy policy. Use of my.psi.cash indicates acceptance of Google’s Privacy Policy and Terms.
Our use of reCAPTCHA is strictly limited to ensuring the continued functioning of my.psi.cash. reCAPTCHA technology performs an automatic analysis for each site request without requiring the user to take any additional actions. This analysis is based on interactions made by the user, and is used to mitigate bot and other malicious behaviour on our website. The data collected during analysis is forwarded to Google, where Google will use this data to determine if you are a human user. This analysis takes place in the background, and users are not advised it is taking place.

When you send an email request to our email auto-responder server, we are able to see your email address. While your email is being processed it is saved to the email server's disk, and it is deleted as soon as it is processed (usually in a few seconds). Your email address may be written to the server system logs. These logs are deleted after one week.
Our email auto-responder server is hosted in the Amazon EC2 cloud. This means that Amazon is able to see the email you send and our response to you.
For each email we receive, we store the following information:
ne1.example.com, but not web120113.mail.ne1.example.com.)Note that if you get Psiphon from an "app store", such as the Google Play Store or Amazon AppStore, additional statistics may be collected by that store. For example, here is a description of what the Google Play Store collects: https://support.google.com/googleplay/android-developer/answer/139628?hl=en
