How to reach us
Use the Contact us button in the corner of this page. It sends your message straight to us; leave your email in the form if you want a reply. Signed in, the same widget appears on every app page as “Report an issue” and attaches the page you were on and your browser version, which saves a round trip of us asking where it happened.
This one channel covers everything:
- Product
- Bugs, uploads that failed, a share link behaving oddly, account changes, deleting your account.
- Billing
- Invoices, refunds, cancellations, tax details. Include the date and amount of the charge. See the Refunds & Cancellation Policy.
- Privacy
- Access, correction and deletion requests, and privacy complaints. Include the email address on the account so we can verify and reply. See the Privacy Policy.
- Security
- Vulnerability reports. Tell us privately first and we will not come after you for looking.
Response times
We aim to answer within 3 business days, and faster than that when something is actually broken. There is no phone support and no live chat — a written report with a link to the affected project gets a real answer quicker than either would.
