How NutriOptio uses cookies and similar technologies

This page explains what cookies and similar local-storage technologies NutriOptio uses on nutrioptio.com, why we use them, and how you can control them. Cookies are small text files stored on your device by your browser. We also use similar technologies such as localStorage and a Service Worker cache in our Pro web app — they are not cookies, but California's CCPA and the EU's ePrivacy rules treat them the same way, so we disclose them here too.

The short version

We use NutriOptio analytics cookies on our public pages so we can see which articles people read. You can turn these off.
We use strictly necessary browser storage (localStorage, a service-worker cache) in the Pro app to keep you signed in and let the app work offline. Turning these off will break sign-in.
We do not use advertising cookies. We do not sell, rent, or share your data with ad networks. There are no third-party trackers on the Pro app.
We do not use cross-site tracking pixels.

What we use, in detail

Name / Key	Set by	Purpose	Lifetime	Type
`_ga`	NutriOptio analytics (on public marketing pages only)	Distinguishes unique visitors so we can count traffic and see which articles work.	2 years	Analytics
`_ga_P9ZGS436CN`	NutriOptio analytics	Persists session state for a single NutriOptio measurement ID.	2 years	Analytics
`np_access_token` `np_refresh_token` `np_user_id`	NutriOptio (localStorage, Pro app only)	Keeps you signed in to your Pro account so you don't have to log in every visit. Not a cookie — never sent to anyone but our own API. Cleared when you sign out.	Until sign-out, manual clear, or 30-day refresh failure	Strictly necessary
`nutrioptio-v##` (Service Worker cache)	NutriOptio (Pro app only)	Caches the app shell (HTML, JS, icons) so the Pro app loads instantly and works on flaky networks. No personal data is stored here.	Until you uninstall the PWA or clear site data	Strictly necessary
Payment-checkout cookies (only on the secure checkout page)	NutriOptio's PCI-compliant payment processor	Fraud detection and session continuity during payment. Only set on the hosted payment-checkout page, never on NutriOptio's own pages.	Up to 1 year	Payment processor

What we do not use

No advertising cookies and no programmatic-ad SDKs.
No cross-site tracking pixels from social networks or ad networks.
No "fingerprinting" or device-graph identifiers.
No session-recording, screen-replay, or heatmap tools.
No data brokers. We do not sell or share personal information as those terms are defined under the California Consumer Privacy Act (CCPA / CPRA).

How to control cookies

1. Turn off NutriOptio analytics on our public site

You have two easy options:

Block analytics cookies in your browser settings. Most modern browsers (Safari, Firefox, Brave, Edge) already block cross-site analytics by default — meaning you may already be opted out.
Send a Global Privacy Control (GPC) signal. Browsers like Brave, Firefox, and DuckDuckGo can send a GPC signal that we honor as an opt-out.
Use private / incognito browsing. Analytics cookies are wiped when you close the window.

2. Clear our local storage in the Pro app

Open your browser settings, find "Site settings" or "Cookies and site data," locate nutrioptio.com, and choose Clear data. This will sign you out and clear the cached app shell. The app will still work — you'll just have to sign in again.

3. Use Do Not Track / Global Privacy Control

NutriOptio honors the Global Privacy Control (GPC) browser signal as a valid opt-out request under the California CCPA. If your browser sends a GPC signal, we will not "sell" or "share" your personal information — though we do not do that in the first place.

4. Delete your account entirely

Pro account holders can delete every record we hold by emailing privacy@nutrioptio.com, or following the instructions on our Data Deletion page.

Changes to this policy

If we add a new analytics or payment partner, we will update this page and refresh the "Last updated" date below before the new partner is enabled.
