# Privacy

Plain language, and checkable against the code. If anything here is not true of what the network actually does, that is a bug and [we want to hear](https://x.com/jrya7) about it.

## What we never do

Stated as refusals rather than as reassurances, because “we respect your privacy” is what every consent banner says.

### No cookies on your site

Not for tracking, not for “analytics”, not for a consent banner we then ignore.

One exception, and it is the only one: if you have an account, a first-party login cookie keeps you signed in to your dashboard. It is set on daylight.ad, never on your site, and nothing else sets a cookie anywhere.

### No fingerprinting

No canvas hashing, no device enumeration, no cross-site graph, no profile.

### Nothing is joined across sites

There is no identifier that survives one page view, so two visits to two sites are two unrelated rows.

## What we do keep

The other half of an honest privacy page: a page that only lists refusals is telling half the story. All of it is either a count or a row about an ad.

### What happens to an IP address

When you click an ad, your address is hashed with a rotating daily salt. The address itself is dropped inside the same request. It is never written to a file, a column or a log we keep.

The salt is deleted after two days. So we can't work backwards from an old hash to an address.

### The rows themselves

- **Impression counts**: One row per date, site and ad. How many times a unit was drawn.
- **Click rows**: Timestamp, which ad, which site, the salted hash, the browser family, whether it was verified.
- **Ad content**: The title, description, and image of the ad only.

### What our homepage remembers

Where you put a card, and not who you are, it is a shared desk. Move something and everyone sees it, and while you are there your pointer shows up under a made-up animal name.

How many people have it open. While you are on the homepage your browser checks in every ten seconds, which is where “here now” comes from, and a check-in is forgotten fifteen seconds after the last one.

Your browser invents a random number and keeps it until you close the tab to tell one visitor from another.

## Getting out, and telling us

The things a reader might actually want to do.

### Taking a listing off

If your product is listed and you would rather it were not, or you run a board whose listings are here, [ask us to take it off](https://daylight.ad/optout). The request is on file and a person does the removal.

### Telling us we’re wrong

Spot something on this page that is not true of the code? email [hello@daylight.ad](mailto:hello@daylight.ad?subject=Privacy%20page).
