Terms

These are the terms for using Sidenote. They are short because the product is.

What Sidenote is

A journaling service that lives in your Messages app. You text a number; Sidenote stores what you send, replies occasionally, checks in around lunch and in the evening, writes a nightly entry from your own words, and answers questions about your past entries.

What Sidenote is not

Sidenote is not therapy, counseling, medical care, or a crisis service. It does not diagnose, score, or advise. If you are in a bad spot, call or text 988 in the US or your local emergency number. Sidenote will tell you the same thing.

Eligibility

Price and billing

Your content

Your journal is yours. You give Sidenote a license only to store, process, and send it back to you as the service requires, using the providers named in the privacy page →. We never train models on it. Export and deletion are always one text away.

Acceptable use

Availability

Sidenote depends on iMessage delivery and third-party providers. We aim for reliability but do not guarantee uninterrupted service or that any message is delivered. If the service ends, we will give at least 30 days’ notice and an export link.

Changes

If these terms change materially, we will text you before the change takes effect.
