Win

Win's device-local storage model means your collection data is as secure as your phone itself, protected by your device's own security features, encryption, and access controls, without any additional layer of cloud security required or potentially compromised. Local storage eliminates the most common source of data exposure for app users: server-side breaches. Because Win's servers hold none of your data, there's no Win database that can be hacked, no credentials that can be phished, and no breach notification you'll ever receive. Your collection is also secure against Win itself changing. If the app is discontinued, changes its business model, or is acquired by another company, your data remains safely on your device, unaffected by any decisions made about the app's future. Device-local security also means your data is immediately available even in high-security environments where app internet access is restricted. A phone in airplane mode or on a secured corporate network can still access Win fully, since no network request is ever needed. Win's local storage keeps your collection, every title, rating, note, and achievement, as private as any other file on your device. No external service, no third party, and no Win itself has access to your personal film and series records.
