Terms
Terms of use
Plain terms for a plain tool. Last changed 31 October 2026.
The service
RiotPad (riotpad.com) is run by WeldonPC. It gives colour calculations (contrast ratios, colour-vision simulations, ramps, harmonies) and exports. The calculations follow the published methods named on the About page; they are information to help you choose colours, not a guarantee that a design is accessible, legible in every setting, or matches any physical colour.
Your palettes
Palettes you make are yours. Palettes kept in a Paint Box are stored so the box can show them to whoever holds its private link. Keep the link safe: anyone with it can open the box. You can delete a palette or the whole box at any time.
Riot Pass
The Riot Pass costs $1.95 a month or $19.50 a year. While RiotPad is in preview, payments are not switched on and every Pass feature is free. When checkout opens, payment is through PayPal; you can cancel at any time from your PayPal account and the Pass runs to the end of the period you paid for. Prices include no hidden fees.
Fair use
Do not try to break, overload or scrape the service. Each connection can make a limited number of changes an hour.
No warranty
RiotPad is provided as it is. WeldonPC is not liable for losses from using the calculations or exports, to the extent the law allows.
