What both publish
| Fact | Guvercin | Spike |
|---|---|---|
| App coverage | all | all |
| Calendar tools | Yes | Yes |
| Free plan | Yes | Yes |
| Platforms | Desktop builds are offered for macOS 11 or later, Windows 10 or 11, and 64-bit Linux; the browser preview is a mock and does not connect to mail accounts. | Spike lists iOS, Android, Windows, macOS, and web browser as supported devices. |
| Privacy | The app has no analytics, telemetry, crash reporting, advertising, or tracking code, and remote images load only when requested. | Spike says it is ad-free and does not rent, sell, distribute, or monetize user data, while non-personal data may be used to improve its service. |
| Product | Guvercin is a desktop email client with a built-in calendar, address book, and task list. | Spike describes itself as an AI-powered inbox that brings email, calls, notes, tasks, and to-dos into one hub and turns email threads into chat-like conversations. |
| Scheduled sending | Yes | Yes |
| Security | Databases use SQLCipher encryption and cached files use XChaCha20-Poly1305; the encryption key is stored in the user profile rather than the OS keychain. | Spike says message data is encrypted with AES-256 using a per-message private key and that it has periodic external security audits. |
| Support | Users can contact support by email or report bugs through GitHub; the maker says replies may take a few days. | The pricing page lists standard support for Starter, priority support for Team and Pro, and VIP support for Business and Ultimate. |
