Do I need privacy analytics?
Published 27 October 2026 · 9 min read
Privacy analytics, or privacy-respecting analytics, counts what people do in your product without recording who they are: no cookies that follow them, no fingerprinting, nothing in the reports that says who anyone is. Whether you need it depends mostly on what you need to know. This article answers the question for a website, an extension and an app, including when the answer is no.
This is not legal advice. Privacy rules differ between countries and between regulators; for a decision about your product, ask someone qualified where you and your users are.
The short answer
You probably want privacy analytics if your questions are about everyone at once:
- how many people use your product, and whether that is growing;
- which pages or features they use;
- whether they come back after a day, a week, a month;
- where new users come from;
- whether the last release helped.
You probably want traditional analytics, or both, if your questions are about particular people: building advertising audiences, following one signed-in customer across their devices, or seeing what one person did. Answering those means identifying people, and identifying people means personal data, with the consent, disclosures and care that come with it.
Neither choice removes every obligation. Privacy analytics makes them smaller; it does not make them disappear.
What you get
- Answers to the product questions. Counts, trends and proportions answer the list above, and none of them needs a name, an email address or a profile.
- Less to disclose. The stores ask what you collect, and so does your privacy notice. The less you collect, the shorter the answers.
- Less to protect. Data you never stored cannot leak or be misused later.
- Fewer rules that bite. Most privacy laws are written around personal information. Collect less of it and fewer of their rules apply, though, as the questions below show, some still can.
For what the practices are in detail, see What privacy-respecting analytics means.
What you give up
It is better to know the trade-offs before you switch than after.
- No individual journeys. You cannot look up what one person did. If you need that for support or billing, it belongs in your own product's records, not in analytics.
- No cross-device linking. The same person on a laptop and a phone counts as two. Google Analytics' User-ID, by contrast, "lets you associate your own identifiers with individual users" so you can connect their behaviour "across different sessions and on various devices and platforms" (Google: User-ID). That is useful, and it is personal data.
- No advertising audiences. Linking Google Ads to Google Analytics lets you "re-engage users based on their behavior in your app or on your site" and build audiences from your analytics (Google: connect Google Ads to Google Analytics). Data that does not follow people cannot do that.
- Counts that are estimates at the edges. People who opt out are not counted; people who clear their storage come back as new. Trends and proportions stay reliable.
When traditional analytics is the better fit
- You run paid advertising and need conversions and remarketing measured in the same place as your site's traffic.
- Your product is built around signed-in accounts and you need each customer's behaviour across devices. That is personal data, and it needs a legal basis of its own.
- Your team already depends on existing reports, and the cost of switching is higher than the cost of the disclosures you already make.
None of these is a reason to measure the whole product that way. Some teams run Google Analytics on marketing pages that carry advertising, and privacy analytics inside the product.
For a website, an extension or an app
A website
A website has no store review, so the obligations come from the law and from your privacy notice. Traditional analytics usually sets cookies: Google Analytics 4, for example, sets a _ga cookie "used to distinguish users", which expires after two years by default (Google: cookie usage on websites).
Dropping cookies does not by itself settle the consent question. France's regulator, the CNIL, says that cookies "are subject to the rule of consent, except in one particular case", and that "subject to a number of conditions, cookies used for audience measurement are exempt from consent". It also notes that the rules may vary between countries (CNIL: use analytics on your websites and applications). What changes when there is no cookie, and what does not, is in Analytics without cookies.
A browser extension
Extensions have two reviews to pass besides the law. In the Chrome Web Store, "you must disclose how your extension collects and uses user data" on the privacy fields of your listing (Chrome: fill out the privacy fields). Firefox has a built-in consent for data collection, which new extensions submitted from 3 November 2025 must use; usage data, technicalAndInteraction, must be optional, so the user can decline it at install (Firefox: built-in consent for data collection). A tool that collects little makes both forms short, and Firefox's consent only works with a tool that sends nothing when the user declines. See the Chrome Web Store privacy practices form and passing Firefox add-on review.
An app
Apple asks for App Privacy details covering "the practices of third-party partners whose code you integrate into your app", and warns that data collected from an app "is often linked to the user's identity, unless specific privacy protections are put in place before collection" (Apple: App Privacy details). Tracking, in Apple's sense, means linking data about a user or device with other companies' data for targeted advertising or advertising measurement, or sharing it with a data broker; from iOS 14.5 it needs the user's permission through App Tracking Transparency (Apple: user privacy and data use). On Google Play, "even developers with apps that do not collect any user data must complete" the Data safety form (Google Play: Data safety section). Privacy analytics does not spare you the forms; it changes what you write on them.
The questions to ask yourself
- What do you actually need to know? Write the questions down before comparing tools. If none of them is about a particular person, you do not need data about particular people.
- Who are your users, and where are they? The rules follow your users, not only you.
- In the European Union, the European Commission explains that data which has been pseudonymised "but can be used to re-identify a person remains personal data"; only data made irreversibly anonymous falls outside the GDPR (European Commission: data protection explained). A random identifier is pseudonymous, not anonymous. See Analytics and the GDPR.
- In Canada, personal information is "information about an identifiable individual", and the privacy commissioner treats information as identifiable where "there is a serious possibility" of identifying someone with it; an IP address "can be considered personal information if it can be associated with an identifiable individual" (Office of the Privacy Commissioner: interpretation bulletin on personal information). See Analytics and Canadian privacy law.
- In California, the Attorney General says Global Privacy Control "must be honored by covered businesses as a valid consumer request to stop the sale or sharing of personal information" (California Attorney General: CCPA). If your analytics feeds advertising, that signal concerns you directly. See Analytics and US privacy laws.
- Are any of them children? In the United States, COPPA imposes requirements on operators of websites or online services "directed to children under 13 years of age", and on others with actual knowledge that they collect personal information from a child under 13 (FTC: COPPA Rule). If your product is for children, take advice before choosing any analytics.
- Will you still need a consent banner? It depends on what the tool stores on the device, where your users are, and how their regulator reads the rules. Privacy analytics can make an exemption reachable where one exists; it does not promise one.
- What will you have to declare? Draft your store answers and the analytics paragraph of your privacy notice for each tool you consider. If one tool's answers make you uncomfortable, that is your answer.
- Who will see the data, and for how long? Your team, the tool's vendor, anyone else? Raw data kept for months or years is a liability; totals are rarely one.

Common questions
Can I use privacy analytics and still identify customers elsewhere?
Yes. Your account system knows who your customers are, as it must. The point is not to copy that identity into your analytics, so that the analytics stays about usage and not about people.
Is a privacy analytics tool automatically lawful?
No tool is. The tool decides what is collected; you decide what you send, what you tell your users and what you ask them. You remain responsible for that.
How AnalyticsTrend does it
AnalyticsTrend is privacy-first product analytics for websites, browser extensions, and mobile, desktop and server apps. It sets no cookies on the people it measures, does not fingerprint them, and collects nothing about who people are unless you put it in an event property. Its identifier is random and scoped to one project, so it cannot be joined to another site or extension. The IP address resolves a country, and in some countries a region, then is discarded. Raw events are deleted after 90 days and daily totals are kept, and reports are shared only with your account's members. On websites a browser that sends Global Privacy Control is not counted at all, unless you turn that off; extensions honour it too where the browser lets an extension see the signal, and Firefox's built-in consent is honoured.
It is designed not to identify anyone, so it gives up what is listed under "What you give up". Its identifier is still stored on the device, so whether you need consent depends on where you and your users are: check what applies to you. You remain responsible for your disclosures and for what you send.
The complete list is in What it collects. To start, see Install on a website, Install in a Chrome extension or Install in an app, which also gives the answers for the App Store and Google Play forms. For an extension's store forms, use the store disclosure helper.
