Drop in a host with optional notes. Your list stays on-device.

- 03

Local reminders fire before Critical / Soon windows hit.
Operators

Protocol
FAQ
- Does it need internet?
- Yes for fresh SSL/RDAP checks. Once dates are stored, you can still view them offline.
- Do you see my domains?
- No. SudoCod does not run a backend for your list.
- Is it a subscription?
- No. One-time purchase on the store—about $1 USD, though the listed price may vary by country or storefront.
- Can I move to a new phone?
- Yes—Android Auto Backup and/or JSON export/import in Settings.
- Will there be an iOS app?
- Planned. Android and iOS purchases are separate unless a cross-platform offer is announced later.
