Nailio Cookies and Similar Technologies

What Nailio stores on your device, and what it does not.

Last updated September 5, 2026

Nailio is an app, not a website

Nailio is a mobile app, not a website, and it does not use cookies.

What is stored on your device

It does store a small amount of data locally on your device so it can work: your sign-in session so you are not asked to log in every time, your theme preference, and a cache of recent content so the app opens quickly. This stays on your device and is removed when you delete the app.

Our website

Our website uses only the cookies needed for the site to function. It does not use advertising or cross-site tracking cookies.

No advertising, no tracking

**Nailio contains no advertising SDK, no third-party analytics SDK, and no advertising identifier.** We do not track you across other apps or websites, we do not build an advertising profile, and there is nothing here to opt out of because there is nothing collecting it.

Usage events stay in our own database, as described in our Privacy Policy.

Clearing what is stored

You can clear everything Nailio has stored locally by deleting the app. Deleting your account removes what we hold on our side, as described on our Data Deletion page.

If this changes

If we ever add a technology that tracks you, we will update this page before that change ships, and we will ask for consent where the law requires it.
