Privacy

Updated November 10, 2026. This page is for Platemark only. Our other products are covered at rowhousesoftware.com/privacy.

Platemark runs on a server, so it keeps some of what you send it. Here's the whole list.

Your account

When you get a key, we save your email, your account id, your plan, how many credits you've used this month and when the account was made. There's no password and no name.

We don't store your API key. We keep a SHA-256 hash of it, plus its first 10 characters so keys can be told apart. Each account also gets a signing secret for signed image links. That one is stored as is, because we need it to check signatures, and GET /v1/account shows it to you.

We don't send email from Platemark, so you won't get a newsletter or reminders. Accounts don't expire. To delete yours, email support@rowhousesoftware.com from the address on the account.

What you send, and what's kept

Template images

Images from POST /v1/images and the render_image tool are made and sent straight back. We don't store the image or the text you sent.

If a slot takes an image link, we download that image to put it in. The download comes from Cloudflare's network, not your device, and Cloudflare may cache it for up to an hour.

Signed image links

With a signed link, the text is in the link itself. The finished image is cached by Cloudflare for up to a year, and anyone with the link can load it. That's the point of these links, since they go in a page's head for social previews.

Charts

Each chart PNG is saved for a year so its link keeps working in emails and docs. Anyone with the link can open it. Links have a random id and we don't list them anywhere, but they aren't private once you share them.

PDFs

Every PDF (invoice, quote, receipt, certificate or letter) is saved for 30 days at a link, and anyone with the link can open it. Whatever you put on the document is in it, so a client's name and address are in there along with the amounts.

Videos

The finished MP4 is saved for 30 days at a link anyone with it can open. The job itself is kept too, with no end date right now: the scenes, their text, the image and music links, and the webhook address if you gave one. When the job finishes, we send its status to your webhook.

The free makers

The maker pages on this site don't need a key. Images and charts from them are made and sent back, not stored. PDFs from them are saved for 30 days like any other PDF, even though no link to them is shown to anyone.

How files are made

PDFs and videos are made in a separate box with no internet access. Its working files are deleted when each job is done.

What we count

• A line for each render: which account, what kind of file, which template or document type, the credits it cost, how long it took, when, and whether it came through the API or MCP. Not what was in it.
• Totals per day of each kind of request MCP clients send, like tools/list or a call to render_chart. Just counts, with no addresses or keys.
• New accounts per IP address per day (the limit is 5) and free maker renders per IP address per day (the limit is 20). We store a SHA-256 hash of the address together with the date, not the address itself, and earlier days are deleted the next time someone uses it. Once paid plans open, requests to start a checkout or open billing are counted per address per day the same way. The limit there is 30.

When something breaks, the error goes to Cloudflare's log for Platemark so we can fix it. An error message can include a bit of what you sent. Our code doesn't log your requests otherwise.

Cookies and your browser

Platemark doesn't set cookies or use local storage. Its pages load fonts and styles from this site only. There are no analytics services, ads or trackers.

Who else is involved

Platemark runs on Cloudflare. Your account, the files above and the counts are stored there, and every request goes through their network, so they see your IP address like any web host would. Their privacy policy covers that.

Sites you point us at see a request from Cloudflare when we fetch an image or music link, or call your webhook. If you use Platemark through an AI app, that app sees the tool results, including file links, under its own privacy policy.

Platemark doesn't send your content to any AI service. We don't sell or share any of this.

Paid plans aren't open yet. When they are, Stripe will handle payments, and this page will say what that adds before it starts.
