Your business data
belongs to
you. Only you.
As an independent professional, you need full control over your client data and invoices. TimeInvoicer was built exactly for that:
✓ Your data stays on your device. All invoices, contacts, and data remain exclusively on your device.
✓ Your own calendar. You use your local Android calendar — no third-party server ever sees your appointments.
✓ Anonymized calendars. Optionally create anonymized calendars — for web sync across devices, room scheduling, or team coordination. No client names exposed. Privacy stays intact.
✓ AES-256 encryption. Optional backups are end-to-end encrypted. Only you hold the key.
✓ Even the automatic recognition happens locally. No data leaves your device — not even for service detection.
✓ GDPR-compliant by Design — Made in Austria. No analytics, no ads, no third parties.
