Cookies
Everything this site stores on your device, who sets it, and how to say no. The consent banner in longer form.
This page lists what is stored on your device when you visit tuomo.co, and how to control it. How personal data is processed is set out at tuomo.co/privacy.
1. The rule
Storing data on your device, and reading it back, is governed by Article 5(3) of Directive 2002/58/EC. It requires your consent, except where the storage is strictly necessary to provide a service you have requested.
This applies to cookies and to equivalent techniques: local storage, session storage, tracking pixels and device fingerprinting.
2. Groups
The banner offers three groups. Analytics and marketing are off until you turn them on. Nothing in either group loads before you answer.
2.1 Necessary — always active
| Item | Type | Provider | Purpose | Lifetime |
|---|---|---|---|---|
tuomo.consent |
Local storage | tuomo.co | Records your cookie choice so you are not asked again on the next page | 12 months, then asked again |
__Secure-next-auth.callback-url |
Cookie | cal.com | Booking view on the contact page | Session |
nextauth.message |
Local storage | cal.com | Booking view on the contact page | Until cleared |
timeOption.is24hClock |
Local storage | cal.com | Clock format in the booking view | Until cleared |
toggledConnectedCalendars |
Local storage | cal.com | Display state in the booking view | Until cleared |
The booking view is embedded from cal.com on the contact page and
loads regardless of your cookie choice, so that booking a call always works. It also requests
content from app.cal.com, lh3.googleusercontent.com and o574544.ingest.us.sentry.io,
which receive your IP address.
2.2 Analytics — off until you consent
| Cookie | Provider | Purpose | Lifetime |
|---|---|---|---|
_ga |
Google Analytics 4 (Google Ireland Limited) | Distinguishes one browser from another | 2 years |
_ga_<container id> |
Google Analytics 4 | Session state for this property | 2 years |
2.3 Marketing — off until you consent
| Cookie | Provider | Purpose | Lifetime |
|---|---|---|---|
_fbp |
Meta Platforms Ireland Limited | Meta pixel — advertising attribution and audience building | 3 months |
_fbc |
Meta Platforms Ireland Limited | Records the ad click that led to a visit. Set only when you arrive from a Meta advertisement | 3 months |
Meta processes this data for its own purposes as well as for advertising measurement on this site, under its own privacy policy.
3. Google Tag Manager and Consent Mode
The analytics and marketing tags load through Google Tag Manager. Tag Manager sets no cookie of its own.
Google Consent Mode v2 runs in basic mode: all signals default to denied, and no request is
made to googletagmanager.com until you consent. Refusing means no request is made at all.
4. Changing your choice
Cookie settings in the footer reopens the banner with your current choices on every page. Changes take effect immediately and stop further loading. Cookies already set on a third-party domain cannot be deleted from here; clear them in your browser.
Your browser can block or delete cookies and site data independently of this page.
5. Changes
Adding or removing anything that stores data on your device updates this page on the same day, and the date at the top with it. Where a change introduces a purpose you have not consented to, the banner asks again.
6. Contact
hello@tuomo.co. Your rights over the personal data behind these cookies are set out in section 9 of the privacy policy.
