Privacy Policy

Last updated: 25 October 2026

InvestP ("the app") is a personal wealth tracker operated by Hoang Nguyen ("we", "us"). This policy explains what data the app collects, why, and the choices you have.

We do not sell your data, use it for advertising, or share it with third parties, except the service providers we need to run the app, as described below.

1. Data we collect

  • Account: your email address, display name and your in-app settings.
  • Financial data you enter: assets, transactions, debts, income, expenses and financial plans, together with the reports and history the app creates from this data.
  • AI analysis: the analyses you request.
  • Paid plans: your current plan and when it expires. We never receive your payment card details.
  • Sign-in and security: technical details about your sign-in sessions, such as IP address and device type, used to protect your account.
  • Feedback you send: the message, a contact email if you choose to add one, and the app version you use.
  • Diagnostics: technical error details together with your account ID, used only to fix bugs. They never include your email, name or financial data.

We do not collect your location, contacts, photos or advertising identifiers, and we do not track you across other apps or websites.

2. Data that stays on your device

  • Your app passcode is kept only in your device’s secure storage and is never sent to our servers.
  • Face ID, Touch ID and fingerprint are handled by your operating system; the app never has access to biometric data.
  • Display preferences such as theme and privacy mode.

3. How we use data

  • To provide the app: store your portfolio and calculate values, performance, cash flow and portfolio insights.
  • To create AI analyses when you request them.
  • To confirm your paid plan.
  • To sign you in and keep your account secure.
  • To answer feedback and support requests and to fix bugs.

We do not use your data for advertising or profiling, or to train artificial-intelligence models.

By creating an account you consent to the processing described in this policy. You can withdraw your consent at any time by deleting your account.

4. Service providers

To run the app we use service providers in the categories below. Each receives only the data it needs for its task:

  • Cloud hosting: runs the app’s servers and stores its data.
  • Email delivery: delivers sign-in emails to your address.
  • Internal tools: help us read and answer the feedback you send.
  • Artificial-intelligence (AI) models: only when you request an analysis and have agreed to it in the app (you can withdraw this in Settings), receive the portfolio or cash-flow data that analysis needs, without your email, name or account ID, and do not use it to train models.
  • Payments and plans: payments are handled by the App Store or Google Play; our subscription provider receives your account ID and purchase details to confirm your plan.
  • Error monitoring (if used): receives only technical error details.

Market prices, exchange rates and similar data come from public market-data sources and are fetched without your identity or your holdings.

We disclose data to authorities only when required by law.

5. Storage and security

Data is stored and processed on our service providers’ servers outside Vietnam. We use appropriate technical and organizational measures, such as encryption in transit and at rest, and restricted access. No method is perfectly secure, but we work to protect your data.

6. Retention

  • We keep your data for as long as your account exists.
  • Sign-in codes and sessions are time-limited and expire automatically. Diagnostic data is kept for up to 90 days.
  • When you delete your account (Settings → Delete account), the account and all its data are permanently deleted immediately. Backups, if any, are overwritten on a regular cycle.
  • Purchase history is kept by the App Store or Google Play under their own policies.
  • Feedback you have sent may remain in our internal tools; email [email protected] if you want it deleted.

7. Your rights

You can view and edit your data in the app at any time and delete your account in Settings. You can also email us to request a copy of your data, a correction, deletion, restriction of processing or to withdraw consent. We will respond as soon as possible and within the time required by law, and may need to verify that you own the account.

How to delete your account, even without the app: Delete your account and data.

8. Children

The app is intended for users aged 13 and over. We do not knowingly collect data from children under 13; if you believe a child under 13 has provided data, contact us and we will delete it.

9. Changes

When we update this policy we change the date at the top. For material changes we will notify you in the app or by email before they take effect.
