AurumBook (operated by Hainan Piazzi Digital Intelligence Technology Co., Ltd.) applies wherever the App is offered on an app store. We collect: device information (for guest-mode login), local financial records you enter, chat and voice transcripts, and membership / entitlement subscription status. Backend services and databases are hosted in Dubai; when you use AI, necessary context is sent over HTTPS to a Singapore LLM node (without sensitive account identifiers) solely to provide AI inference; speech-to-text prefers on-device recognition and may use cloud recognition when needed (without sensitive account identifiers). You can Clear Data or Delete Account in Settings. Contact: service@piazzi.vip. Full details are in the sections below.
This Policy applies to:
This Policy does not apply to:
The App is intended for users aged 13 and older (or the higher minimum age required in your country). If you are under 18, you should use the App with the knowledge and consent of a parent or legal guardian.
We do not knowingly collect personal data from children below the applicable minimum age. If you believe a child has provided us data without proper consent, contact service@piazzi.vip and we will take appropriate steps to delete it.
We collect only data reasonably necessary to provide personal finance tracking, budgeting, AI assistance, membership / entitlement subscriptions, and in-app purchases of AI credits.
| Category | Examples | Purpose |
|---|---|---|
| Account & profile | Nickname, language, currency preference, AI assistant nickname & personality; optional email and password for account recovery | Personalise the App and restore data on a new device |
| Financial records | Income/expense amounts, categories, dates, notes, budgets, savings goals | Core bookkeeping |
| AI interactions | Text messages to Aurum AI, parsed transaction drafts, voice-derived text | AI chat & voice logging |
| Gift & social records | Gift registry entries (names, amounts, occasions) if you use this feature | Optional feature |
| Support enquiries | Emails or messages you send to support | Customer service |
| Category | Examples | Purpose |
|---|---|---|
| Device information | Device identifier used for guest-mode login, app instance ID, OS version, app version | Guest login, authentication, security |
| Usage & diagnostics | API request logs, error logs, membership / entitlement and AI credit counters, first-party in-app analytics events | Service operation, abuse prevention |
| Notifications | Local scheduled reminders only — no push token is collected or uploaded | Optional reminders you enable in Settings |
We do not currently use third-party advertising networks or sell your personal data.
| Permission | Why we ask | Can you refuse? |
|---|---|---|
| Microphone | Voice input for expense logging via Aurum AI | Yes — use text/manual entry instead |
| Speech recognition | Convert voice to text — on-device first; cloud speech recognition when needed (see §8) | Yes |
| Photos / media | Save your Money Persona card to your photo album | Yes — bookkeeping still works |
| Notifications | Budget and bookkeeping reminders you enable | Yes — leave off in Settings or disable in system settings |
We request permissions at runtime where required by the OS and only for the stated purposes.
Optional membership / entitlement subscriptions and AI credit packs are processed by the app store from which you downloaded the App (independent in-app billing per store). We receive purchase / subscription status and receipts (e.g. product identifier, fulfilment status, whether entitlements are active) but not your full payment card or bank account numbers. Prices are shown only on the store purchase screen and are not listed in this Policy.
We use personal data to:
We do not use your financial data for third-party advertising profiling.
Depending on the processing activity, we rely on one or more of the following bases under the UAE PDPL and other applicable privacy law:
| Basis | Application |
|---|---|
| Consent | Optional features (notifications, voice input, saving images to Photos, AI chat beyond essential service) |
| Contract | Providing the App and in-app purchases you request |
| Legitimate interests | Security, fraud prevention, service improvement (balanced against your rights) |
| Legal obligation | Compliance with applicable law in your country, or court/regulatory requirements |
Where consent is required, you may withdraw it at any time through App settings or by contacting us — without affecting processing already lawfully performed.
AurumBook includes Aurum AI, which uses automated processing and third-party large language models (LLMs) to:
When you use Aurum AI (chat, understanding after speech-to-text, expense draft parsing, deep report insights, and similar features), requests are forwarded by our backend over HTTPS to a third-party LLM service. The current LLM inference node is located in Singapore. Prompt text and context required to deliver those features are transmitted to and processed in Singapore solely to provide AI inference, and without sensitive account identifiers such as passwords or full payment card numbers.
We apply a minimum necessary principle. The backend does not place the following sensitive information in LLM request bodies, including but not limited to:
To provide AI features, we may send to the Singapore LLM node text or summaries directly required for that request, for example: messages you type and recent chat turns, draft transaction fields before you confirm them, and aggregated report statistics needed for insights (such as category totals or period-over-period changes — not a full database dump). Any text you voluntarily type into chat bubbles (including amounts, merchant names, and notes) may enter LLM context. Do not paste passwords, full card numbers, national ID numbers, or similar sensitive raw strings into chat.
We use trusted processors who handle data on our instructions:
| Provider type | Role | Typical data shared | Location |
|---|---|---|---|
| Cloud hosting | App backend, database, cache | Account, transactions, chat history | United Arab Emirates (Dubai) |
| AI / LLM provider | Chat, parsing, report copy | Feature-related prompts and context (see §7) | Singapore (inference node) |
| Speech recognition | Voice-to-text | On-device first; when needed, audio or transcript segments are forwarded via our backend to cloud speech recognition. We do not attach account IDs, email, passwords, or device identifiers to those speech requests | On-device and/or cloud processing nodes as required |
| App store | In-app purchase billing for AI credits | Purchase tokens / fulfilment status | Per that platform’s policy (independent per store) |
We do not name specific speech or model brands in this Policy. A current list of sub-processors is available on request at service@piazzi.vip.
The App backend services and databases are hosted in the UAE (Dubai). When you use Aurum AI, prompt text and context required for that feature are sent over HTTPS to an LLM inference node in Singapore solely for AI inference (without sensitive account identifiers). When cloud speech recognition is used, necessary audio or transcript segments may be forwarded through our backend to the relevant processing node (also without sensitive account identifiers).
Where required by the UAE PDPL or other applicable privacy law, we implement appropriate safeguards such as:
By using AI and cloud features, you acknowledge such transfers may occur for the purposes described in this Policy.
| Data type | Retention |
|---|---|
| Active account data | While your account exists and you use the App |
| Purchased AI credit balances | Available during the validity period shown in the App; then expire |
| Deleted transactions / chat (Clear Data) or account deletion | Removed or anonymised from active systems; backups may persist up to 90 days |
| Server logs | Typically 90–180 days, unless needed for security investigations |
| Purchase / billing records | As required by tax/accounting law (often 5–7 years) |
| Inactive guest accounts | May be anonymised or deleted after 24 months of inactivity |
We may retain anonymised or aggregated data that cannot identify you.
We implement appropriate technical and organisational measures, including:
No method of transmission or storage is 100% secure. You are responsible for keeping your device secure and not sharing your login credentials.
Subject to applicable law, you may have the right to:
| Right | How to exercise |
|---|---|
| Access | Request a copy of personal data we hold about you |
| Rectification | Correct inaccurate data in the App or via support |
| Erasure | Settings → Clear All Data (chat & transactions); Settings → Delete Account (full account); or email service@piazzi.vip with subject “Account Deletion Request” |
| Restriction | Ask us to limit certain processing |
| Portability | Request export of your data in a machine-readable format (available on reasonable request) |
| Objection | Object to processing based on legitimate interests |
| Withdraw consent | Disable optional features or contact us |
We will respond within 30 days (or any shorter period required by the privacy law of your country), after verifying your identity. Billing records may be retained where required by law. We may refuse requests that are manifestly unfounded, excessive, or prohibited by law.
Settings → Clear All Data removes your chat history and transactions from active service databases while keeping your guest/account identity so you can continue using the App.
Use Settings → Delete Account, or email service@piazzi.vip with subject “Account Deletion Request”. We will:
Deletion may be delayed where retention is required by law (e.g. billing records). Backups may persist for up to 90 days.
We do not send unsolicited marketing email or SMS. Service-related notices (e.g. critical updates) may still be sent.
Local reminders are opt-in via the in-app Settings toggle and system notification permissions. We schedule them on your device only; we do not collect a push notification token for this feature.
We may update this Policy to reflect legal, technical, or business changes. When we make material changes, we will:
Continued use after the effective date constitutes acceptance of the updated Policy.
