Rainbow is provided by Going Stellar SRL. By installing it you agree to these terms. If you do not, uninstall it — that is the whole remedy and it costs nothing.
The effects listed on the Pro page as free are free, with no time limit and no user count. We do not intend to move them behind payment. If we ever changed our mind, anything you had already applied to your documents would stay exactly as it is — the colours live in your document, not in our add-on.
A Pro licence is $29 a year or $69 once, and unlocks the Pro features of Rainbow. A team licence covers every add-on we publish, for a whole organisation. A licence key is for one person, on up to three Google accounts. Keys issued before 20 October 2026 unlock Pro in every add-on, as they always did. If a licence lapses, Rainbow returns to the free palettes; nothing is removed from your documents.
Refunds: write to us within 30 days and we refund, no questions asked.
Rainbow changes formatting in your document. It has a preview and a one-press undo, and we test it hard, but you are responsible for your own documents — keep the version history that Google Docs™ gives you. The add-on is provided “as is”, without warranty of any kind. To the extent the law allows, our liability is limited to what you paid us in the previous 12 months.
You can uninstall at any time. We may discontinue the add-on, in which case anything already applied to your documents is unaffected and any unused part of a paid year is refunded.
