# Privacy

_I take your privacy serious and give you full control over it._

You can [change your consent](https://homepage.sefzig-net.workers.dev/questions#consent) anytime.

## Your data

My Homepage does not collect data from you.
All data you provide is saved locally in your browser.

I receive data only if you give me the [consent](https://homepage.sefzig-net.workers.dev/questions#consent) for "Tracking" and-or "Marketing":
* _Tracking_ will show me your behavioral data (pages visited, links clicked, etc.).
* _Marketing_ will send your data to [Posthog(cxw tooltip click)]("I use [Posthog](https://posthog.com/) as my CDP (Customer Data Platform)."), so that I can communicate with you even when you are not on my Homepage.

Your data is also sent to me when you have given me the "Functional" consent and use communicative functions like the Annotations.

## Consent categories

_You can activate certain data categories._

You can activate the following categories, which all serve the specific purposes explained here.

Necessary* [^]
  My Homepage gives your browser one [stable id](preferences://show?group=profile&box=person), which is saved as a server-side cookie. I need that id to persist the [Preferences](preferences://show?group=profile) you choose. Required.

Tracking [v]
  I use [Posthog(tba)](https://posthog.com/) to track visitors of the Homepage and see session replays. Feel free to opt-out, even though this blinds me a bit when looking at my traffic.

Functional [v]
  My Homepage is personalized using app-internal data and cohorts calculated in my CDP [Posthog(tba)](https://posthog.com/). You can switch Personalization off, but I beg you not to.

Marketing [v]
  I would like to reach out to you (via email) in case I think something new might interest you. You can switch off my [Posthog(tba)](https://posthog.com/) outreach completely.

## Third parties

_Understand which services are used here._

A list of all external services that may get your data, including how you can manage the transfer by adjusting your consent:

* _Cloudflare_: My Homepage is hosted and thus tracked by Cloudflare.
* _Posthog_: In my CDP, I automate email communication with you.
* _Slack_: Annotations and contact forms are sent to my Slack.
