What to expect

What helps us fix it faster

Do not send us passwords. We never need one, and we will never ask for one.

Getting your data out

You never need us for this. Sign in as the owner, open your account menu (your picture, top right) and choose Export data, and you get a zip of spreadsheets covering your business’s records. It works while your subscription is active and it keeps working if it lapses.

Billing

Manage your subscription, update a card or download an invoice from Billing in your account menu on the web. A plan bought in the iPhone app is billed by Apple, so you change or cancel it in Settings on your iPhone. For anything else, email us.

Reporting a security issue

Email help@quarterlybooks.com with “security” in the subject. Tell us what you found and how to reproduce it. We will acknowledge within one business day and keep you updated until it is closed. Please give us a reasonable chance to fix it before publishing, and please do not access, change or delete data belonging to anyone else while investigating. We will not pursue anyone who reports in good faith and stays within those lines.

Status and incidents

If Quarterly is down or degraded, we will email subscribing businesses rather than leaving you to guess. When it is over you get a short account of what happened and what changed as a result.
