It should look like it came from you.

Upload two versions and the right one is used in each place: a wide lockup for headers, and a square mark for tight spaces. Provide only one and it stands in for the other; provide neither and you get a clean initial tile rather than a broken image.

• →The public sign-up page — the first thing a new attendee ever sees.
• →Every personal schedule page, for attendees and instructors alike.
• →Printed schedules and saved PDFs, on the header alongside your organisation name and the project dates.
• →The header of every schedule email that goes to an attendee or an instructor.
• →The app itself, so your own team sees your mark rather than ours.

Each project can also carry its own colour, which is useful once you are running several at once.

Removing every trace of us is not. You cannot put the pages on your own web address: public pages live on ours. They also carry a small "Powered by ScheduleSorter" line at the foot, on every plan — everything above it is yours. The emails we send on your behalf keep our name in the footer too. If a completely unattributed experience is a hard requirement, this is the wrong tool and it is better to know that now.

Logos are accepted as PNG, JPEG or GIF, up to 1 MB. SVG is refused — an SVG is a document that can carry script, and it would run on the same origin as your attendees' pages. Replacing a logo takes effect immediately rather than waiting on a cache.

People with no sessions in a published schedule are deliberately skipped rather than sent an empty timetable. The instructor wording is genuinely different from the attendee wording, not the same email with a word swapped.

This is the part that saves the most goodwill. When you publish a change, you are not limited to emailing the entire project again — you can send to only the people whose week is actually different between the old schedule and the new one.

The difference is worked out from the two schedules themselves, so it is the real difference, not a guess. Someone whose sessions did not move hears nothing. Someone whose class moved is told which class, from when, to when. Someone who lost their place is told that plainly, in its own line, rather than being left to compare two timetables and work it out.

Or aim it wherever you need

Everyone

The whole project — attendees, instructors, or both.

One group

Just the Beginners, just Year 9, just the Saturday crowd.

One person

For when a single conversation went sideways.

Only those affected

Worked out from the difference between the two schedules.

Every schedule email carries a real unsubscribe, including the one-click header that Gmail and Outlook now expect. Opting out is recorded against the email address and the kind of message, not against one project — so someone who is both an attendee on one project and an instructor on another opts out once and it holds everywhere.

• →Clicking the link shows a confirmation page rather than unsubscribing on the spot, so a corporate link scanner cannot silently opt someone out.
• →Resubscribing is offered on the same page, for the people who clicked it by accident.
• →If an address does not exist, or someone reports the email as spam, we stop sending to it automatically, without you doing anything.
• →Account and billing messages are never stopped. Nobody should miss a password reset because they opted out of timetables.

Your own attendee-facing mail deliberately does not carry your logo when it is an account or billing message from us — those are ours, and dressing them up as yours would be misleading.

Every email we try to send is recorded with what happened to it — delivered, failed, skipped, blocked, bounced. When somebody says they never got their schedule, that is a question with an answer rather than a shrug. Opt-outs are listed too, and you can resubscribe someone who asks to come back.

• →No SMS and no push notifications. Email only.
• →No automatic reminders before a session. Emails go out when someone signs up and when you publish, not by the clock.
• →No marketing email to your attendees. Their addresses are yours; we do not use them.
