Privacy Policy
Last updated: 8 August 2026
Summary
Gratuity Calculator: Simple & Fast does not collect personal information. There are no accounts, no logins and no user database. Everything you enter in the app is processed on your device and discarded when you close it. This website is an information and privacy reference for the app and does not calculate anything or collect anything either.
Information we collect
None. We do not collect your name, email address, phone number, postal address, contacts, location, restaurant details, payment-card or banking information, identity documents, microphone audio or camera images.
Bill amounts and calculations
Bill amounts, gratuity percentages, split counts, tips and totals are calculated entirely on your device. They are never transmitted to us or to any third party, and they are not written to persistent storage.
Local preferences
Your selected currency, your recently used currencies, your default gratuity percentage and your theme choice are stored locally on your own device. This data never leaves the device and contains no personal identifiers. Clearing the app's storage removes it permanently.
AI and verification processing
The gratuity calculation is performed by a deterministic on-device engine. The independent verification layer also runs on your device. No bill amount, percentage or calculation is sent to an external AI service, and the product does not require a network connection to calculate.
Third-party services
The website is served by our hosting provider, which processes standard technical request data such as IP address and user agent for the purpose of delivering the page and protecting the service. We do not operate an application backend, and no calculation data is sent to any third party.
Analytics and advertising
Gratuity Calculator: Simple & Fast contains no advertising, no advertising identifiers and no cross-site tracking. We do not build profiles and we do not sell or share data, because we do not hold any.
Permissions
The product requests no sensitive permissions: no camera, microphone, location, contacts, SMS, phone, Bluetooth or nearby-device access. Currency suggestions come from your operating system's language and region settings, never from geolocation.
Security
The site is served over HTTPS. No API keys or secrets are embedded in the client, and no calculation data is transmitted, so there is no stored user data to breach.
Data retention and deletion
We retain nothing. Because all data stays on your device, deletion is entirely under your control: clear the app's storage in your device settings and every stored preference is gone.
Children's privacy
Gratuity Calculator: Simple & Fast is a general-audience gratuity calculator that collects no personal information from anyone, including children.
Changes to this policy
If the implementation changes in a way that affects privacy, this policy will be updated and the date above revised. The policy will always describe what the product actually does.
