Privacy note.
This is deliberately short, because the site collects almost nothing. Last updated 6 November 2026.
What we collect
If you contact us through the form we store the email address you submit, the category of product you say you're building, and the time of the request. We do not use advertising trackers, third-party analytics or session recording on this site.
Why we collect it
To contact you about the leftspin runtime. Nothing else. We do not sell, rent or share your address with third parties for marketing.
Where it lives
Contact submissions are stored by the deployment that serves this site or forwarded to a private team inbox. If you deploy this site yourself, you control that storage.
Removal
Reply to any email you receive from us and ask, and we will delete the entry. Deletion is manual and happens on request.
Product data, later
When you run the hosted runtime, the data you send through it is yours. A DPA, retention controls and regional deployment are available on Dedicated and bring-your-own-cloud plans. This note will be replaced by the contractual terms at that point.
