# Safe App > Safe App prevents chargebacks and recovers disputed payments for merchants on Stripe and Shopify. Stopper stops chargebacks before the bank is notified. Disputer fights the disputes that are filed. Disputer is priced on results: a success fee is charged only when a dispute goes the merchant's way. There are no setup fees and no monthly subscription on standard pricing. Safe App is operated by Curiously Tech LLC. Merchants connect their payment provider in under 60 seconds and follow every case from the dashboard or the Safe App mobile apps for iOS and Android. How Disputer billing works: - The success fee is a percentage, shown on the pricing page. - It is charged for a chargeback that is won, on the amount returned to the merchant. - It is also charged for an inquiry that Safe App responded to and that closes without becoming a chargeback, on the disputed amount the merchant keeps. An inquiry is a request from the card issuer before any chargeback is filed. Its fee is charged when the inquiry closes, which on Stripe can be up to 120 days after it opened. - If a dispute is lost, there is no fee. Stopper is billed per alert handled. Higher-volume merchants can get custom pricing. ## Products - [Disputer](https://www.safe.app/disputer): Picks up new disputes from connected accounts, gathers evidence, drafts a response for the reason code and submits it to the payment provider before the deadline. - [Stopper](https://www.safe.app/stopper): Monitors the merchant's payment descriptor across Visa and Mastercard and intercepts disputes before the bank is notified, so they can be resolved as refunds with no fee and no dispute record. - [Pricing](https://www.safe.app/pricing): Current Disputer success fee, Stopper per-alert price and custom pricing, with a pricing FAQ. - [Book a demo](https://www.safe.app/demo): A 15-minute walkthrough of how Safe App handles disputes end to end. ## Help - [FAQ](https://www.safe.app/faq): Questions about Disputer and Stopper, including setup and how the two products differ. - [Support](https://www.safe.app/support): Contact options for merchants and prospects. ## Policies - [Terms](https://www.safe.app/terms): Legal terms, including performance-based billing in section 7. - [Privacy Policy](https://www.safe.app/privacy): How Safe App collects, uses and shares data. - [Cookie Policy](https://www.safe.app/cookies): Cookies the site uses and how to change the cookie choice. ## Blog - [Blog](https://www.safe.app/blog): Guides on chargebacks, dispute management and fraud prevention for online merchants. ## Optional - [Gaming PC chargebacks](https://www.safe.app/blog/gaming-pc-chargebacks-ai-disputer): How gaming PC sellers can cut chargebacks with automated dispute responses. - [Shopify red flags for gaming PC orders](https://www.safe.app/blog/shopify-red-flags-gaming-pc-orders): Warning signs of fraudulent gaming PC orders on Shopify. - [Stolen card fraud on PC components](https://www.safe.app/blog/red-flags-stolen-card-fraud-pc-components): Spotting stolen card fraud in electronics orders. - [Stripe fraud rules for high-ticket electronics](https://www.safe.app/blog/stripe-fraud-rules-high-ticket-electronics-merchants): Stripe fraud rules and what they mean for high-ticket electronics merchants. - [Fraud patterns in camera gear on Stripe](https://www.safe.app/blog/red-flags-fraud-patterns-camera-gear-stripe): Fraud patterns camera gear sellers see on Stripe, and automating dispute responses. - [Refund policies for camera stores](https://www.safe.app/blog/refund-policies-camera-store-fraud-defense): Using refund policies as a defense against fraud. - [Mobile-first dispute management for PC component sellers](https://www.safe.app/blog/mobile-first-dispute-management-pc-component-sellers): Managing disputes from a phone. - [Mobile-first dispute automation for camera stores](https://www.safe.app/blog/mobile-first-dispute-automation-camera-stores): Automating dispute responses for camera stores. - [Mobile chargeback tools for hobbyist gear](https://www.safe.app/blog/mobile-first-chargeback-tools-hobbyist-gear): Chargeback tools for hobbyist gear sellers.
