Privacy Policy

Last updated: 21 October 2026

Who we are

Perfume DNA (perfume-dna.com) is an independent fragrance discovery project run by an individual based in Slovakia. For any privacy question or request, email hello@perfume-dna.com.

The short version

You don’t need an account to use Perfume DNA, and we don’t offer one. There are no forms that send us your details (you can email us if you want to), no ads, no advertising trackers, and we don’t sell data. When you tap “I have it” or “Love this note”, we add one to a public, anonymous count — nothing about you is stored.

What stays on your device

Some choices are kept in your browser’s local storage on this device, so the site remembers them between visits. They are never sent to us:

• the perfumes you save;
• the perfumes you mark “I have it” and the notes you love;
• the notes you mark as “want” or “avoid”, so other pages can show your match score;
• whether you closed the storage notice.

This storage only does what you ask it to — remember your own picks — so it doesn’t need your consent. That’s why the notice at the bottom of the page has a single “OK” button: it tells you where your data lives, it doesn’t ask permission. We don’t set advertising or tracking cookies.

You can remove saved perfumes on the Saved page, or delete everything by clearing this site’s data in your browser settings. “Share my list” uses your device’s own share menu or clipboard; nothing passes through our servers.

The backup link on the Saved page carries your lists inside the link itself, after the “#” sign — browsers don’t send that part to any server, including ours. Anyone who has the link can see the perfume and note names in it, so keep it for yourself or share it only with people you choose.

Anonymous counts

When you tap “I have it” on a perfume page or “Love this note” on a note page, your browser asks our counter service (a small program run on Cloudflare Workers) to add one to that perfume’s or note’s total, or to take one away when you undo it. We store only the totals, for example “Vanilla: 12”. We don’t store your IP address, any identifier, or anything that links a tap to you or your device, and no cookies are used. Your browser remembers your own taps (see above), which is how one browser counts once.

To stop anyone from tapping hundreds of times in a row, the service briefly keeps track of how many taps came from the same connection in the last minute. This is held in memory only, never saved, and gone within minutes. The totals are shown on the site, for example “12 people love Vanilla”.

Hosting and security

The site is delivered by Cloudflare. Like any web host, Cloudflare processes technical data such as your IP address and browser type to deliver pages and protect the site from abuse. We use this only to run and secure the site.

Fonts

The fonts on this site (Fraunces and Inter, both open-source) are stored on our own server and load together with the page. Your browser doesn’t contact Google Fonts or any other font service.

Visit statistics

We use Cloudflare Web Analytics to count page visits in aggregate. It does not use cookies or collect personal data, and we use the totals only to understand which pages are useful, for example to show which brands were explored most this month. It is currently not loaded for visitors in the European Union.

If you email us

If you write to hello@perfume-dna.com, we receive your email address and whatever you include in the message. We use it only to reply to you. Mail sent to this address is forwarded by Cloudflare to a Gmail inbox (Google), where it is stored. We delete correspondence when it is no longer needed, and at the latest two years after our last exchange, unless you ask us to delete it sooner.

Links to other websites

Perfume pages link to web search and other websites so you can find a fragrance. When you follow a link, you leave Perfume DNA, and that website’s own privacy policy applies.

Legal basis

We process the limited technical data described above on the basis of our legitimate interest in running a secure, working website, the short-lived tap limit described under “Anonymous counts” on the basis of our legitimate interest in keeping the counts honest, and emails you send us on the basis of our legitimate interest in answering them (GDPR Article 6(1)(f)).

How long data is kept

Saved perfumes, your collection, loved notes and note choices stay on your device until you remove them. Anonymous counts and visit statistics are kept only as totals. Emails are kept as described above. Cloudflare keeps technical logs for a limited period under its own policies.

Your rights

You can ask us for access to, correction of or deletion of personal data we hold about you, and you can object to processing. Write to hello@perfume-dna.com. You can also complain to the Slovak data protection authority (Úrad na ochranu osobných údajov Slovenskej republiky) or to the authority in your own country.

Children

Perfume DNA is a general-audience site and doesn’t ask anyone for personal data.

Changes

If we add a feature that collects data, such as emailing your list, we will update this page before launching it and change the date above.
