Line by line
The lines that matter most, worst first.
Ad companies can use what you do on JetBrains sites plus other sites to show you targeted ads elsewhere.
Read the exact line
Privacy policy
“These advertising partners may use this information (and similar information collected from other services) to deliver personalized advertisements to you when you visit digital properties within their networks.”
For example, visiting kotlinlang.org could help an ad network later show you JetBrains ads on another website.
Under California-style rules they treat some tracking as a sale or share for ads, even if no cash changes hands.
Read the exact line
Privacy policy
“we may “sell” or “share” the following categories of personal information: identifiers, internet and network activity information, location data (via your IP address), and inferences.”
For example, your IP and browsing on their site may be given to ad networks unless you opt out.
This notice does not say whether your AI prompts train models; that is in a different policy they do not include here.
Read the exact line
Privacy policy
“If you are using JetBrains AI, we or our LLM providers may collect personal data related to your AI service usage. For more information, please consult our dedicated policy.”
For example, you cannot tell from this page alone if a Kotlin AI chat is used to train an LLM.
They list building marketing-style profiles from your data, without saying you can view or edit that profile.
Read the exact line
Privacy policy
“Inferences drawn from other personal information to create a profile about a consumer: Profile reflecting a consumer’s preferences, characteristics, psychological trends, predispositions, behavior, attitudes, intelligence, abilities, and aptitudes.”
For example, they might infer you are a likely buyer of a paid IDE from how you use the site.
Even after you ask for deletion, copies can stay in logs and backups.
Read the exact line
Privacy policy
“We may also have copies of your information in application logs, weblogs, and/or backups made for security and support purposes”
For example, an old support ticket might still sit in a backup after your account is removed.
They describe real encryption (TLS in transit, AES-256 at rest) rather than a vague “we take security seriously.”
Read the exact line
Privacy policy
“We encrypt your data in transit and at rest where it is technically feasible.”
For example, your account data on their servers is supposed to be stored with AES-256 when they can.
They set a 13+ default and ask for a parent email if someone says they are under 13.
Read the exact line
Privacy policy
“Our products and services are generally not designed for and are not offered to children under the age of 13.”
For example, a 12-year-old filling a form should trigger a parent-permission email, or the data is deleted in three days.
They claim they do not collect health or other special-category personal data.
Read the exact line
Privacy policy
“We do not process health data or otherwise sensitive data about you.”
For example, they say they are not gathering medical or religion fields as part of this notice.
There is a website opt-out for cookies and personalized ads, but it is per device and browser.
Read the exact line
Privacy policy
“You may stop or restrict tracking by clicking on the “Opt-Out” link in the footer of our Website.”
For example, turning off tracking on your laptop does not opt out your phone.
Some collection can be turned off in the account or product settings, not only by email.
Read the exact line
Privacy policy
“You may manage your Personal Data in your JetBrains Account, including by opting out of certain kinds of data collection.”
For example, you might switch off some product analytics in your JetBrains Account.
Words to know
Legal words from the lines above, in plain English.
- personal data
- Any information that is about you or can be linked to you, from your name to your phone's ID. For example, your email, your IP address and the list of apps on your phone are all personal data.
- third parties
- Any company or person other than you and the app, such as advertisers, partners or analytics firms. For example, an analytics company that receives a record of every screen you tap is a third party.
- retention
- How long a company keeps your data before deleting it. For example, a policy might keep your messages for 30 days after you delete them, or for as long as it likes.
- targeted advertising
- Ads chosen for you based on what you have done across other apps and websites, not just this one. For example, you look at shoes in one app and see shoe ads in a totally different app the next day.
- sell or share
- Under California law, selling means passing your data to others for money or other value; sharing means passing it on for targeted ads. For example, letting an ad network use your browsing history in return for ad space counts as a sale.
- precise geolocation
- Your exact position, usually from GPS, often accurate to within a few metres. For example, an app can tell not just your city but which building you are in right now.
- profiling
- Building a picture of who you are, what you like and what you might do next from your data. For example, an app may guess your income, health or politics from what you watch and tap.
- sensitive personal information
- Data that could hurt you if exposed, like health, religion, sexuality, race, exact location or bank details. For example, telling a chatbot about a medical condition creates sensitive data that some laws protect more strictly.
- opt out
- Something is on by default and stays on until you find the setting and turn it off. For example, your chats may be used for training unless you go into settings and switch it off.
