What We Collect

The privacy notice for RenewCity's optional play-data sharing. Last updated 1 October 2026.

RenewCity can share a small amount of anonymous information about how the game is played. It is off unless you turn it on, it is never tied to you or to your computer, and the game plays exactly the same way whichever you choose.

This page is the complete list. If it is not written here, it is not recorded.

Unlike some administrations, we publish our records.

Why we ask at all

One question: how far into the game do players actually get? A demo can be finished by its developer a hundred times and still lose everybody at the same unmarked corner. Knowing which quarter people reach, and which panel was open when they stopped, is the difference between fixing that corner and guessing at it.

What we record

What we never record

Who you are to us

One random number, made on your machine the first time you said yes, stored beside your saves. If you turn sharing off it is deleted; if you turn it back on, a brand-new one is made — a return visit is a new stranger, not a returning one. It is not derived from anything about you or your computer.

With no connection, batches wait in a small capped file next to your saves and go out on a later launch. Turning sharing off deletes that file too, so nothing gathered under a consent you withdrew is kept.

Your IP address

Every request on the internet carries the address of the computer that made it. That is how a reply finds its way back, and no website can opt out of it. So it is worth being exact about the difference between what the network sees and what we keep.

Seen, briefly: when the game sends a batch, our hosting provider (Cloudflare) receives the connection and therefore sees the originating IP address, in the ordinary course of routing and of blocking abuse.

Stored by us: nothing. Our collector never reads the address, never writes it into a record, and never puts it in a log. There is no field for it in any stored file, and no log stream that retains one is switched on. An address is never joined to the random id above — doing that would turn an anonymous id into an identifying one, which is the exact thing this design exists to prevent.

Outside our control: Cloudflare keeps its own network-level records for security and abuse prevention, under its own privacy policy. Apart from the one setting below, we do not configure, receive, or query those records, and they are never connected to the game's data. We say so here rather than pretending the layer beneath us does not exist.

The one setting we do control: a rate limit at Cloudflare's edge, which stops floods of fake data before they reach our collector. When it blocks one, Cloudflare's security log records the blocked address for a short time, where the developer can see it in the Cloudflare dashboard. We never export that log or connect it to the game's data.

Where it goes, and for how long

Batches are stored as plain text files in Cloudflare R2 object storage, in a bucket only the developer can read. They are grouped by the date they arrived and by nothing else — the filenames contain no identifier of any kind.

Records are kept for 18 months and then deleted.

They are read by one offline script that counts how many players reached each stage. There is no dashboard, no third-party analytics service, and no account anywhere that holds this data.

Changing your mind

Settings → Privacy, at any time, in either direction. Turning it off deletes the random id and any batches still waiting to be sent. If you declined at first launch, you will not be asked again.

Getting your records removed

Write to privacy@renewcitygame.com. One person reads that mail: the developer.

Because the records hold nothing that identifies you, we need the one handle that does exist: the random id. The game shows it to you — Settings → Privacy → What We Collect, under "Who you are to us". Send that, and the matching records are deleted. Without it there is genuinely nothing to search for, which is a consequence of the design rather than an excuse.

The formal part

Some privacy laws, including the EU and UK GDPR, ask for these facts in so many words. Here they are.
