Cookie Policy

Last updated: November 5, 2026

1. What cookies are

Cookies are small text files that a website stores on your device when you visit it. They are used to remember information about your visit, such as your preferred language or other settings, to make your next visit easier.

2. Necessary cookies we use

naiara_session — Necessary/technical. Keeps you signed in. httpOnly (not accessible via JavaScript), expires after 30 days.

NEXT_LOCALE — Necessary/technical. Remembers your chosen language so you don't have to pick it on every visit. Expires after 1 year.

Google sign-in state cookie — Necessary/technical, very short-lived (10 minutes). Used only during the Google sign-in process for security purposes.

naiara_cookie_consent — Necessary/technical. Remembers the choice you made about this Cookie Policy so we don't ask again on every visit. Expires after 1 year.

__stripe_mid and __stripe_sid — Necessary/technical, set by Stripe, our payment provider, for fraud prevention. They are set on every page because the payment component loads with the site. __stripe_mid expires after 1 year; __stripe_sid after 30 minutes.

These necessary cookies don't require your consent because they are essential for the Site to function, under Article 22.2 of the Spanish LSSI-CE.

3. Analytics cookies (require your consent)

Naiara's own statistics. Besides Google Analytics, we measure how the Site is used with our own tool, hosted on our servers with no third parties: pages visited, time on each page, how much is read, where you came from and your approximate location (country, region and city), derived from your IP by our network provider (Cloudflare) without us storing the IP.

naiara_vid — First-party. Only set if you accept the “Analytics” category. It identifies your browser with a random value so we can see your path through the Site across visits and, if you sign in, link it to your account. It expires 13 months after your last visit and is deleted as soon as you withdraw consent.

If you do not accept, we set no analytics cookie: your visits are only counted in aggregate (no identifier on your device and no way to link one visit to another on a different day).

We use Google Analytics 4 (Google Ireland Limited) to understand how the Site is used: page views, traffic sources and most-used features. It is only activated if you accept the "Analytics" category in the preferences panel.

_ga — Distinguishes visitors. Expires after 2 years.

_ga_<ID> — Keeps the analytics session state. Expires after 2 years.

These cookies are not set until you accept. We use Google Consent Mode: until you decide, Google's script loads and may receive cookieless, aggregated browsing data, including your IP address, which is anonymised. As soon as you reject, no analytics cookie is set.

You can read how Google uses this data at policies.google.com/technologies/partner-sites.

Our own heatmaps. If you accept the "Analytics" category, we record on our servers where you click, where the mouse travels and which buttons or links you press on public pages, to improve their design. It is stored added up per page and day, with no identifier, for 90 days, and cannot replay anyone's visit. We do not record what you type or the content of your files, and we do not use heatmaps on your account pages.

4. Advertising cookies (require your consent)

We use the Meta pixel (Meta Platforms Ireland Limited) and Google Ads signals to measure how our advertising performs and to show relevant ads. In addition, on the website's converter and PDF tool pages we show Google AdSense ads (Google Ireland Limited) to people who are not Naiara Plus subscribers. This is a separate category from analytics and is accepted or rejected separately.

_fbp — Set by Meta to identify your browser for advertising purposes. Expires after 3 months.

_gcl_au — Set by Google to measure ad conversions. Expires after 3 months.

Google AdSense cookies (for example __gads, __gpi, __eoi) and Google privacy message cookies (FCCDCF, FCNEC) — Set by Google to serve ads, limit how often you see each one, measure their performance and remember your answer to its message. Google acts as an independent controller for ad personalisation. Their duration is set by Google, up to 13 months.

_fbp and _gcl_au are not set unless you accept the "Advertising" category. Meta and Google may process this data outside the European Economic Area under the European Commission's standard contractual clauses.

Google AdSense ads have their own message: in the EEA, UK and Switzerland, Google asks you before using these cookies, and if you do not accept it can only show non-personalised or limited ads. In US states with privacy laws you can opt out with the link in the footer or the Global Privacy Control signal. In other countries Google applies local rules, and you can turn off personalisation at adssettings.google.com. The desktop app shows no ads, and Naiara Plus subscribers see no ads.

The Meta pixel script does not load until you accept the "Advertising" category. The Google AdSense tag does load on the Site's public pages, because it is what shows Google's privacy message; ads only appear on the converter and PDF tool pages.

5. Local storage

In addition to cookies, we use your browser's local storage to remember your appearance preference (light, dark or automatic mode). This is not technically a cookie and is never sent to our servers, but we mention it for transparency.

6. Managing your preferences

You can change your decision about non-essential cookies at any time via the "Your Privacy Choices" link in the Site's footer.

If you are in the US, the "Your Privacy Choices" link in the footer opens these same options. We also honour your browser's Global Privacy Control signal: when it is on, we treat "Advertising" as refused. You can change your answer to Google's message from "Your Privacy Choices", under the Google ads option.

You can also configure your browser to block or delete cookies. Note that blocking necessary technical cookies may cause some Site features (such as staying signed in) to stop working correctly.
