Privatum
Privacy Policy
Effective 19 October 2026
The short version: this site has no analytics, no ads and no trackers. We set one cookie, and only if you sign in to the beta. We never sell or share your personal data.
1. Who we are
Inkfernal is developed and published by Ian Greenberg ("we", "us"). This policy covers this website, the Inkfernal beta (the Windows download and the browser version) and the online co-op service that connects players.
2. This website
The site has no analytics, no advertising and no third-party trackers. Its pages, pictures, fonts and scripts are all served from our own address; nothing on it loads from another company's servers.
All traffic to the site passes through Cloudflare, which protects and delivers it. Cloudflare sees your IP address and the details of each request (such as the page asked for, your browser's user agent and the time) and handles them under Cloudflare's own privacy policy.
Our server receives your IP address with each request. It uses it in memory to limit abuse (for example, too many sign-in attempts) and does not save it to a database. The server also writes operational logs, such as errors and the page that caused them, which we use only to keep the service running. These logs do not record IP addresses, and they are deleted automatically after 14 days.
3. Cookies
We set exactly one cookie, and only when you sign in to the beta with the beta password:
- inkfernal_beta: a signed token holding an expiry time and a random value. It contains nothing about you. It lasts 30 days, or until you sign out, and is only sent back to this site, so the beta downloads and the browser version know you are signed in.
This cookie is strictly necessary to give you the beta you asked for, so no consent banner is needed. We never set any other cookies: no analytics, advertising or tracking cookies of any kind.
4. The beta sign-in
The beta password is checked on our server only. We never store or log the password you type. To slow down guessing, the server counts sign-in attempts per IP address in memory; each count fades within a minute or two and is never written to disk.
5. Online co-op
When you host or join a co-op game, your game connects to our relay server, which passes game data between you and your partner. To do that it sees your IP address, which it uses in memory to limit connections and new lobbies per address.
A lobby holds a temporary four-letter code, the game's build version, the hero you picked and, if the game sends one, a display name. Your partner's game sees those details, as it must to play with you. Everything lives in memory for the length of the session (plus about 30 seconds to let a dropped connection rejoin) and is forgotten when the lobby closes or the server restarts. The relay forwards game packets; it does not store them.
Where co-op runs through Steam instead, Steam carries the connection, and your Steam display name is shown to the other player as the host's name. Steam's privacy policy applies to that.
6. The desktop game
- Saves stay on your computer, in the game's data folder. If you play through Steam with Steam Cloud on, Steam may sync them for you.
- Your SteamID is read from the Steam client on your computer to name your save folder and to run Steam co-op lobbies. We do not send it to our servers.
- A local log file (
logs/main.login the game's data folder) records technical details for troubleshooting and may include your Steam display name. It never leaves your computer unless you choose to send it to us. - Crash reports. Builds that ship with crash reporting switched on send a report to Sentry (Functional Software, Inc.) when the game crashes or hits an error. A report contains the error and its stack trace, the game's version, and technical details of your system such as the operating system and graphics hardware. Crash reporting is set up so that it never sends your IP address, your name or any account details, cookies or web headers, and it records no usage or play sessions. You can turn it off in the game under Settings, Play, "Send crash reports" (it takes effect the next time the game starts), or by launching the game with
--no-crash-reports(in Steam: the game's Properties, then Launch Options). Sentry handles reports under Sentry's privacy policy.
7. The browser game
The browser version keeps your save in your browser's local storage, on your device. It is never uploaded. Clearing this site's data in your browser erases it. Co-op in the browser uses the relay described above. The browser version sends no crash reports.
8. Steam
When Inkfernal is on Steam, Valve handles your Steam account, purchases, Steam Cloud saves, achievements and friends. Valve's privacy policy applies to all of that.
9. How long we keep things
| What | Where | How long |
|---|---|---|
| Your IP address for rate limits | Our server's memory | Minutes; never written to disk |
| Co-op lobby details | Our relay's memory | Until the lobby closes (plus about 30 seconds) |
| Operational logs | Our server | 14 days, then deleted automatically |
| Beta cookie | Your browser | 30 days, or until you sign out |
| Saves and local logs | Your device | Until you delete them |
| Crash reports | Sentry | As long as needed to fix the bug, within Sentry's retention limits |
10. Selling and sharing
We do not sell your personal data, and we do not share it for advertising. The only outside companies involved are the ones named above (Cloudflare, Sentry and, on Steam, Valve), each doing the job described.
11. Children
Inkfernal is not directed at children under 13, and we do not knowingly collect personal data from them. If you believe a child under 13 has sent us personal data, contact us and we will delete it.
12. Your rights
Wherever you live, you can ask us what personal data we hold about you, and ask us to correct or delete it. We hold very little that can be tied to you, so we may need your help to find it (for example, the email you wrote to us from).
In the EU, EEA and UK (GDPR), you also have the right to restrict or object to processing, to data portability, and to complain to your local data protection authority. We rely on our legitimate interests to keep the site and co-op secure and working and to fix crashes, and on providing the service you asked for when you join the beta.
In California (CCPA/CPRA), you have the right to know, delete and correct personal information, and to opt out of its sale or sharing. We do not sell or share personal information, and we will never treat you differently for using your rights.
To make a request, email [email protected]. We will answer within the time the law requires.
13. Where data is processed
Our server and the providers named above may process data in the United States and in other countries. Where the law requires it, those transfers are covered by the providers' own safeguards, such as standard contractual clauses.
14. Changes to this policy
If we change how we handle data, we will update this page and its effective date. For significant changes, we will also say so on the site.
15. Contact
