Private financial control by ShareCapsule
Your money.
Your device.
Your control.
Plan income, spending, debt, savings and goals without giving ShareCapsule readable financial data. Compare your spending with transparent BLS-based regional and income peers, learn through the Financial Control Guide, build additional income projects, and optionally keep trusted devices synchronized with encrypted ciphertext only.

Your financial action plan
This planner uses transparent rules and your local numbers. No financial data is sent to an AI service.
Planning guardrail
This tool is for education and personal organization. It does not know your complete tax, legal, insurance, investment or family situation and is not a substitute for a qualified professional when a decision has significant consequences.
Security center
Your privacy controls
Financial information should be treated as highly sensitive. Local-only remains the default; encrypted sync is optional.
Encrypted storage
The vault is encrypted with AES-GCM. The encryption key is derived from your passphrase using PBKDF2-HMAC-SHA-256 with a unique random salt. Only encrypted ciphertext, salt and initialization vector are persisted.
Optional zero-knowledge sync
When you enable device sync, the browser can connect only to the dedicated ShareCapsule sync relay. The relay stores encrypted vault ciphertext and cannot decrypt it without your vault passphrase.
Automatic lock
The decrypted working copy stays in page memory. To let the same browser tab move between ShareCapsule pages without asking for the passphrase again, the 256-bit vault key is wrapped locally with a non-extractable device key and kept only in session storage. The session expires after inactivity or when you press Lock vault; the passphrase itself is never stored.
No credential collection
Never enter bank usernames, passwords, card numbers, full account numbers, Social Security numbers or authentication codes here.
Export / import records
Before moving to a new ShareCapsule Finance domain, export one portable encrypted records file. It contains the encrypted finance vault and, when present, Income Lab progress. Your vault passphrase is still required on the new domain. Device-sync credentials are intentionally not exported.
Keep this file private and do not delete the old-domain data until you have imported and verified the new domain.
Erase this device
Permanently remove the local encrypted vault from this browser.
