Terms of Service

Last updated: 25 July 2026

These Terms of Service ("Terms") form a binding agreement between you and M. R. Viana ("Recallo", "we", "us") governing your access to and use of the Recallo website and applications (the "Service"). By purchasing a licence, creating an account or using the Service, you accept these Terms.

1. What Recallo is

Recallo is a collection of memory games for iOS, Android and web browsers. Games record your score and adjust difficulty to your performance.

2. Eligibility

You must be at least 18 years old to purchase a licence. An adult may purchase a licence and set up an account for a player under 18, in which case that adult remains responsible for the account and for compliance with these Terms.

3. Your licence

On payment of the one-time fee we grant you a personal, non-exclusive, non-transferable, revocable licence to use Recallo for your own non-commercial use, on devices you personally control, for as long as we continue to offer the Service.

"Lifetime licence" means access for the operational lifetime of the product without further payment. It does not mean the product will exist in perpetuity. If we ever discontinue Recallo we will give registered users at least 90 days' notice and provide a full export of their score history.

3.1 What you may not do

• Share, resell, sublicense, rent or transfer your account or licence key.
• Copy, decompile or reverse-engineer the Service, except where that restriction is prohibited by law.
• Manipulate scores or leaderboards, or use automated tools to play.
• Circumvent usage limits, security measures or licence checks.
• Use the Service to distribute unlawful or malicious content.

We may suspend or terminate accounts that breach this section. Where a breach is minor and capable of remedy, we will normally warn you first.

4. Your account and your data

You are responsible for keeping your login credentials secure. Your score history belongs to you: you may export it as CSV at any time and request deletion of your account. We do not sell it or share it with advertisers. See the Privacy Policy.

5. Price and payment

• The current price is USD 90, charged once. This is not a subscription and does not renew.
• The price shown at checkout is what you pay; applicable tax or VAT is displayed before you confirm.
• There are no in-app purchases and no advertising inside the app.
• Payment is handled by our third-party payment processor, whose terms also apply to the transaction.
• We may change the price for new customers at any time. A change never affects a licence already purchased.

6. Refunds

You may request a full refund within 30 days of purchase, for any reason. The procedure is in our Refund Policy, which forms part of these Terms. Statutory withdrawal rights, where they apply, are in addition to this policy and are not limited by it.

7. Availability and support

We aim to keep the Service available at all times but do not guarantee uninterrupted availability. Support is by email at contact@recallo.com, normally answered within two business days.

8. Content and games may change

We add, revise and occasionally retire games. Scoring scales may be recalibrated, which can change historical figures. We will not reduce the Service below what was described at the time of your purchase without offering you a refund.

9. No guarantee of results

We make no promise, express or implied, that use of Recallo will produce any particular score, rate of improvement, or any benefit to memory, attention, learning, work performance or health. Any figures or examples shown on our website are illustrative only.

10. Disclaimer of warranties

To the fullest extent permitted by law, the Service is provided "as is" and "as available", without warranties of any kind, express, implied or statutory, including implied warranties of merchantability, fitness for a particular purpose and non-infringement. Some jurisdictions do not allow these exclusions, so parts of this section may not apply to you.

11. Limitation of liability

To the fullest extent permitted by law, our total aggregate liability arising out of or relating to the Service is limited to the amount you paid us in the twelve months before the event giving rise to the claim. We are not liable for indirect, incidental, special, consequential or punitive damages, or for lost profits, lost data or lost opportunity.

Nothing in these Terms excludes liability for death or personal injury caused by negligence, for fraud, or for any liability that cannot lawfully be excluded. If you are a consumer, your statutory rights are unaffected.

12. Termination

You may stop using the Service and request account deletion at any time. We may suspend or terminate your licence if you materially breach these Terms. On termination your right to use the Service ends; you may request an export of your score history for 30 days afterwards.

13. Changes to these Terms

We may amend these Terms. If a change is material we will notify registered users by email at least 14 days beforehand. Continued use after the effective date constitutes acceptance.

14. Governing law

These Terms are governed by the laws of Brazil, and the courts of Brazil have exclusive jurisdiction. If you are a consumer resident elsewhere, you retain the protection of mandatory provisions of the law of your country of residence.
