Contact
One address, read by a person. It is outside the tool, so do not attach a private series.
Support
Email support@focusstacks.com. Expect a reply within a few days, not hours; some mail — spam, requests to add features the site has ruled out — gets no reply.
Reporting a stack that failed
Say which browser and device, how many frames, their size, and what the result panel's checks said (frames aligned, correlation range, crop). Two frames from the series at reduced size are usually enough to reproduce a problem; please do not send a whole bracket unless asked.
What this address is not
It is not a way to have a stack merged for you, and it is not a channel for legal notices about a photograph you did not take — the site holds no photographs.
