Privacy Policy
Last updated: 15 November 2026
Short version: Seriesfold runs in your browser, your artwork stays on your device, and we collect only what we need to sell you a license, answer you and fix problems.
Who is responsible
Seriesfold is operated by Xiaodong Ma, an individual based in Kunming, Yunnan, China. Contact: support@seriesfold.com.
What we collect
- Your designs: nothing. Box sizes, character names and uploaded images are processed locally in your browser and never sent to our servers.
- Stored in your browser: if you activate a license key, the key, a random browser ID and the activation ID are saved in your browser's local storage so you stay unlocked. You can remove them in the app at any time. We set no advertising or tracking cookies.
- Help & feedback form: when you send a message we store what you wrote, the topic you chose, your email if you give one, and technical context shown to you before sending: the page address, your browser and screen size, language, and — inside the app — the box type, dimensions and plan you were using. Cloudflare tells us your country. We do not store your IP address; a one-way salted hash of it is kept for up to 20 minutes only to stop spam floods.
- Purchases: our merchant of record Creem collects your name, email, billing country and payment details. We receive your name, email, what you bought and your order / license information. We never see your full card number.
- Emails: if you write to us, we keep the conversation so we can help you.
- License checks: when you activate a license, your key and a random browser ID are sent through our server to Creem to confirm the key is valid; the result may be cached on our server for up to 24 hours. Nothing about your designs is included.
- Statistics: we may use Cloudflare Web Analytics, a cookieless service, to count page views. It does not build profiles of individual visitors and does not track you across sites.
- Hosting logs: our host, Cloudflare, processes technical data such as IP address and browser type to deliver and protect the website.
We do not use advertising trackers, and we do not sell or rent your personal data.
Why we use it
To deliver and secure the website, to provide your license and paid features, to answer questions and fix the problems you report, and to meet tax and accounting obligations.
Who we share it with
- Creem (payments, tax, receipts, license keys and license checks)
- Cloudflare (hosting, security, statistics, feedback storage and email forwarding)
- Our email providers, to receive and answer messages (including forwarding feedback to our inbox)
These providers may process data outside your country. We only share what each needs to do its job.
How long we keep it
Feedback messages are deleted automatically after 12 months (sooner if you ask). Order records are kept as long as tax and accounting laws require (typically several years). Support emails are kept for up to 3 years after the last message, unless you ask us to delete them sooner.
Your rights
You can ask us to show, correct, export or delete the personal data we hold about you, or object to how we use it. Email support@seriesfold.com and we'll reply within 30 days. You can also contact your local data protection authority.
Children
Seriesfold is a professional tool and isn't directed at children under 16.
Changes
If we change this policy we'll update the date above, and for significant changes we'll tell customers by email.
