Terms of use
Effective November 9, 2026.
Sellazo is a service of PROLAT, LLC (United States) that lets businesses give digital stamp cards to their customers. By creating your account you accept these rules. Questions? Write to hola@prolatagency.com.
Your account
You must be of legal age and give true details about your business. Keep your password and your counter PIN safe: whatever is done with them (stamps, rewards, offers) counts as done by your business, including by someone on your team.
Plans and billing
When you create your account you pick a plan and use it free for 10 days, without a card. If you add your card earlier, the first charge is still on day 10. If the days run out without a card, or if you cancel your plan, you can no longer stamp or sign up new customers until you activate it; your customers and their stamps stay saved.
Prices are in US dollars on the plans page. The plan is charged in advance, monthly or yearly, and renews automatically until you cancel it. Stripe charges your card; we never see or store its number. If we change a price, we tell you at least 30 days before and it applies from your next renewal. If a charge fails, your account is paused until the payment goes through: no stamping, no new customers and no notifications. Your customers and their stamps stay saved and everything comes back as soon as you pay.
Cancelling
Cancel anytime in “Your plan” → “Manage my plan”, no calls. Everything keeps working until the end of the period you already paid for, and you are not charged again.
Refunds
If it is your first payment and you ask within the first 14 days, we refund it in full. After that we don’t refund partial periods, but you can cancel so it doesn’t renew.
Your customers and their data
Your customers’ data belongs to your business, and your business is responsible for it. Sellazo stores and processes it on your behalf, only to keep track of their stamps and send what you decide; we don’t sell it or use it for anything else (see the privacy notice).
You are responsible for letting your customers know you keep their data, for sending offers only to those who agreed to receive them, and for honoring the rewards on your card.
What’s not allowed
Using Sellazo for anything illegal, sending misleading or unwanted notifications, offering rewards you won’t give, or trying to get into another business’s account. If that happens, we may suspend the account.
The service
We do our best to keep Sellazo always working, but there may be failures or maintenance pauses. Some parts depend on others (Apple Wallet, Google Wallet, phone notifications and Stripe) and can change without us deciding it. Sellazo is provided as is: if something goes wrong, the most we are liable for is what you paid us in the last 12 months.
If the account is closed
You can download your customers to Excel before leaving. If the account is closed for non-payment or for breaking these rules, we email the account address and give you time to download your data. After closing it, we delete it with its data when you ask us to.
Changes
If we change these terms, we tell you by email or in your dashboard before they apply. They are governed by the laws of the United States and the State of Utah.
