Ultra-low-latency personal finance command center, multi-account ledger, and productivity workspace built on Cloudflare Workers, D1 database, R2 storage, and Firebase Authentication at wallet.devnivo.shop/.
Accounts, transaction ledgers, personal profile cards, tasks, and files are stored natively on Cloudflare D1 and R2 for instant edge reads and writes—no Google Drive access is required on login.
Logging in requests only standard identity claims (openid, email, profile) paired with server-side HttpOnly HMAC cookies and owner-verified access control.
Users may optionally authorize two-way Google Tasks and Google Calendar event synchronization strictly to keep due blocks and reminders up to date.
Devnivo Wallet adheres strictly to the Google API Services User Data Policy (including Limited Use requirements). User data is never sold, shared for ads, or used to train generalized AI models.
