2. What are cookies?
Cookies are small files stored in your browser when you visit a website. They can remember your preferences, help a website function, measure how it is used, or support advertising.
Similar technologies, such as browser session storage, can temporarily store information needed by website features.
Some cookies are stored under our website’s domain, including cookies used by external services. Others are stored under a service provider’s own domain.
3. How we use cookiesEssential cookies and storage
These support necessary website functions and remember your cookie choices. They are not controlled by the optional analytics and advertising switches.
Our website uses Tilda’s consent cookies to remember whether you have made a choice and which categories you have allowed.
Our booking form also uses browser session storage to retain booking-confirmation information during your browsing session.
Analytics cookies
With your permission, we use Google Analytics 4 to understand how visitors use our website, including which pages they visit and how they interact with it.
This helps us assess website performance and improve the visitor experience. Analytics information can include browser and device information, page views, referral information and cookie identifiers.
Google Analytics tracking is not activated until you allow analytics cookies.
Advertising cookies
With your permission, we use Google Ads and Meta advertising technologies to measure advertising performance and support advertising audiences and relevant advertising.
These technologies can associate website interactions with advertising identifiers. Google and Meta may combine information collected through their technologies with information they hold, subject to their policies and your settings.
These advertising technologies are not activated until you allow advertising cookies.
4. Main cookies used on this website
The following first-party cookies were identified in our website checks:
Google documents a default lifetime of up to two years for its Analytics cookies. Browser restrictions can shorten this period; our Chromium check showed approximately 400 days. Cookies can be renewed during subsequent use when the relevant category remains enabled. See Google’s cookie documentation.
Browser settings, consent choices and interactions with external services can affect which cookies are present. Google’s additional advertising cookies are described in its advertising and measurement cookie reference.
Cookie expiry is separate from the retention period for information already collected by a service.
5. Your choices
When the cookie banner appears, you can:

• Select Accept All to allow analytics and advertising cookies.
• Select Reject All to refuse optional cookies.
• Open Cookie Settings to choose analytics and advertising separately.

You can change your choice or withdraw consent at any time using the Cookie settings button on our website.
Rejecting optional cookies does not prevent you from browsing our website or using our booking form.
Withdrawing consent stops the relevant tracking on subsequent use. It does not undo processing that took place before withdrawal or automatically delete information already held by service providers.
You can also delete or block cookies through your browser settings. Deleting our preference cookies will cause the website to ask for your choice again. Blocking all cookies can affect some website functions.
6. External services and international processing
Our website is built using Tilda. We also use Google Analytics, Google Ads and Meta technologies as described above.
These providers can process information outside the European Economic Area, including in the United States. Information about their processing locations, retention practices and applicable transfer safeguards is available in their policies:

• Google Privacy Policy
• Meta Privacy Policy
• Tilda Privacy Policy

7. Appointment bookings
Cookie consent is separate from the information needed to process an appointment request.
When you make a booking, the details you submit are processed through our booking service and Altegio to manage your appointment. Refusing analytics or advertising cookies does not prevent this processing.
Please refer to our Privacy Policy for information about booking data, retention and your data-protection rights.
8. Changes and contact
We will update this policy when our use of cookies or the services on our website changes.
For questions about this policy or your personal data, contact contact@denoisebcn.com.
You may also contact the Spanish Data Protection Agency, Agencia Española de Protección de Datos (AEPD), regarding data-protection concerns.
9. Our own booking attribution and browser storage
With your analytics consent, DE | NOISE uses its own booking-attribution system
to associate a website referral or advertising source with a booking reference.
This helps us understand which sources lead to appointments. This optional
processing is separate from providing salon services: you can book without it.
We do not copy your name, phone number or email into this attribution dataset.

We use the last known non-direct source within 30 days before the booking.
The source can include an allowed source category, medium and numeric campaign
identifier. Advertising click identifiers are retained only if you also allow
advertising cookies. Unknown sources remain unidentified; this system does not
identify every visitor or reconstruct missing historical advertising information.

Our website uses these local-storage entries in your browser:

• denoise.source.v1: stores the permitted referral or advertising source for
the 30-day attribution window. It requires analytics consent. Advertising
click identifiers additionally require advertising consent.
• denoise.withdraw.v1: stores random withdrawal tokens and technical references
needed to apply your privacy choices to bookings made through this browser.
These tokens are used for privacy controls, not advertising or cross-site
identification. They can remain for up to 12 months while relevant attribution
links exist, or while a withdrawal request is awaiting successful delivery.

Local storage is specific to the website origin and browser. Entries are checked
and removed on subsequent use; a closed browser may retain expired local entries
until the site is used again or you clear its storage. Expired entries are not
used for attribution.

On our server, advertising click identifiers are retained for no more than
90 days from their collection. A source-to-booking link is retained for up to
12 calendar months from preparation of the booking request, without extending
that period when the data is read or retried. Unconfirmed source information is
limited by the original 30-day attribution window. Technical withdrawal markers
may be retained until the original link expires to prevent erased information
from being restored by delayed processing. These limits do not change the
separate retention rules for salon appointments, accounting records or Google
Analytics.

Changing your cookie settings to refuse analytics removes the local source
and requests removal of the related internal attribution links known to this
browser. Refusing advertising requests removal of the advertising click
identifiers. Requests are retried if our service is temporarily unavailable.
An encrypted local recovery copy is retained for at most one hour and is
invalidated when a withdrawal for a known link is accepted.

This withdrawal does not cancel your appointment, delete operational records
in Altegio, or automatically erase information held by Google or Meta. If you
clear browser storage, use another device, or cannot complete an automatic
withdrawal, contact contact@denoisebcn.com and provide your booking reference
where available so that we can help with your request.
