Hey Monkey is an expense management app developed and operated by an individual, Pham Vu Nhat Minh. This policy describes how we collect, use, and protect your data when you use the app. By using Hey Monkey, you agree to this policy.
Last updated: July 16, 2026
Account information (email, display name); data you enter or confirm: transactions, categories, budgets, bill-splitting groups (including names of people you add yourself), and recurring transactions; notification and appearance preferences; content you send to the AI assistant (chat messages, receipt images, and text converted from voice); a device token for push notifications; purchase/subscription information when you upgrade; and technical crash data used to fix bugs.
To run the logging, budgeting, reporting, and group bill-splitting features; to extract transactions with AI and suggest amounts and categories (you always confirm before saving); to send notifications you have enabled; to process paid-plan upgrades; and to improve app stability. We do not sell your personal data to third parties.
When you use AI features, your chat messages and receipt images are sent to our AI provider (OpenAI) to categorize, extract, or analyze spending. For the voice feature, your speech is converted to text using your operating system's speech recognition (Apple on iOS, Google on Android) - depending on the device, this may run on-device or via that provider's services, subject to their own privacy policies. The audio recording is NOT sent to Hey Monkey's servers; only the resulting text is sent to the AI. Receipt images are processed transiently and then discarded; they are NOT stored. Data sent to OpenAI is used only for extraction and is not used to train models, per their API policy. You should avoid sending overly sensitive information when not necessary, and always review and confirm the result before saving.
Hey Monkey offers a paid plan (Hey Monkey Pro). On Android, payments are processed through Google Play Billing; on iOS, through the Apple App Store. We do not receive, see, or store your card details. RevenueCat helps us manage subscription status. Hey Monkey does not connect to real bank accounts and does not automatically access your bank transactions unless explicitly stated in the future.
Hey Monkey uses: Supabase (authentication and database), Amazon Web Services (running AI processing), OpenAI (AI extraction), Resend (sending system emails), Expo (push notifications), RevenueCat, Google Play Billing and the Apple App Store (processing paid-plan payments), and Sentry (crash monitoring, with personal information removed). These providers process data only to deliver the service for Hey Monkey.
Hey Monkey may collect: email and account info, user-entered financial data, receipt images, text from voice input, a device identifier (push token), and diagnostics/crash data. This data is used to: provide app features, sync your account, run AI processing, send notifications, improve stability, and support users. We do not sell your personal data to third parties.
Your data is kept until you delete it. Receipt images and voice are NOT stored on our servers - they are processed transiently and then discarded. You can delete your entire account and data directly in the app (Settings), or export your transaction data to a CSV file. See the Delete Account page for details.
Data is transmitted over encrypted HTTPS/TLS, passwords are stored as hashes by the authentication system, and login sessions are encrypted on your device.
You can access, edit, export, and delete your data at any time in the app. You can withdraw consent by ceasing to use the app or deleting your account.
Hey Monkey is not intended for anyone under 13. We do not knowingly collect data from children below this age.
We may update this policy over time. Significant changes will be announced in the app or on this page, along with a new update date.
For any privacy questions or data deletion requests, please contact support@heymonkey.app.
