Prism is provided by Going Stellar SRL, Str. Zizinului 667, Tărlungeni 507220, Brașov County, Romania (“we”). By installing or using the add-on you agree to these terms.
Prism applies colours, size ramps and an upside-down effect to the text you select, in Google Docs™ and Google Slides™. The paid feature lets you use your own colours instead of the built-in palettes. All changes are ordinary edits in your file and can be undone with Ctrl+Z.
Every effect is free: palettes, gradients, random colours, growing letters and flipped text, in both apps. Using your own colours requires a licence key: $29 per year or $69 once. A licence is personal and may be used by the person or organisation it was issued to.
If a licence expires, the paid features stop and everything that was free keeps working. We do not lock you out of your own files.
Write to us within 30 days of purchase and we refund the payment in full, no questions asked.
Your documents remain yours. We do not receive, store or process their contents — see the privacy policy.
Do not attempt to resell the add-on, to circumvent the licence check, or to use it to violate the terms of Google Workspace™.
The add-on is provided “as is”. To the extent permitted by law our total liability is limited to the amount you paid for the licence in the twelve months before the claim. Nothing here limits liability that cannot be limited by law.
We may update these terms; the date above shows the last change. Material changes will be announced on this page.
Romanian law applies, with the courts of Brașov County having jurisdiction, without prejudice to any mandatory consumer protections in your own country.
