Account and profile information
Online services process information needed to provide your account and app features, such as your email address, name, region, selected tax/vehicle settings, Terms acceptance, subscription entitlement and account-access status.
Terms agreement evidence
When you accept the Terms in the app, we retain the accepted version, a SHA-256 hash of the exact document, your account ID, the full name you type as an electronic acknowledgment (for newer acceptances), the server acceptance time, your business-use confirmation and a client build label. Authorised admins can inspect the exact version and typed name you accepted with; each admin view is logged. Earlier acceptance records may not have a verified document hash. This proof is separate from your private income and tax records, and does not collect an IP address. After account deletion, the limited agreement proof is ordinarily removed within 24 months; an active legal dispute or legal requirement may require longer retention.
Private driver records
Income, expenses, logbook records, tax calculations, vehicle details, IRD/GST numbers, receipts and source screenshots are private app records. They are not published to Driver Community and are not exposed to other drivers.
Encrypted cloud recovery backup
Tax Diary NZ can maintain an account-bound encrypted latest recovery backup and dated encrypted archives in private cloud storage. The requested design keeps usable account records for up to ten years while the account remains active, subject to a tested retention and capacity policy. Account deletion removes ordinary backup objects. A limited agreement/deletion proof may remain for 24 months after deletion or longer under a documented legal hold. The recovery objects are associated with your signed-in account and protected by storage access rules. It is intended to help restore your records after device loss or replacement.
Driver Community
If you use Driver Community, the display name, @username and content you choose to post can be visible to other signed-in Community users. Community moderation records may be retained where reasonably required for abuse prevention and safety.
Support and bug reports
Support conversations, bug reports and attachments are stored online so the support team can respond. Admin replies and moderation notices may generate app notifications.
App-health diagnostics
Tax Diary NZ keeps a short rolling diagnostic history to help investigate crashes. The design stores task names, timestamps and app version information rather than financial values, tax amounts, kilometres, notes, message contents, receipts or passwords.
Derived analytics
Where enabled, Tax Diary NZ may upload limited derived benchmark information needed for features such as Earning Score. It is designed not to upload the underlying private ledger entries used to calculate those metrics.
Event map
The Assistant map downloads map tiles directly from OpenStreetMap when you view it. OpenStreetMap receives the network request, including your IP address and the map area requested. Event pins come from published event listings; regional pins are labelled approximate when a venue location is unavailable. Tax Diary NZ does not ask for your device location for this map.
Google Play subscriptions
Google Play handles subscription payment and trial eligibility. Our backend checks purchase tokens with Google Play to grant account access and stores a hash of each linked token. Admin blocks and finite complimentary access are recorded separately from Play billing.
Service providers
Tax Diary NZ uses service providers for authentication, database/storage, website hosting, email delivery, app distribution/billing and live data. Provider details may change as the product develops.
Your choices
You can export your data, manage backup options, sign out and request account deletion. See the account deletion page for current instructions.
