Privacy Policy

Last updated: October 19, 2026 · Applies to all AIsier Inc. apps, including AIsier Invest

Who we are

AIsier Inc. is a Delaware, USA corporation that builds AI-powered consumer mobile applications, registered at 131 Continental Dr, Suite 305, Newark, DE 19713, United States. We are the data controller for the information described below. Contact: privacy@aisierinvest.com.

What we collect

We only collect what a feature actually needs. Everything below is tied to your account and is used to operate the app, never to profile you for advertising.

• Account data: e-mail address, username, chosen language and currency, your app preferences, and the date you accepted our Terms.
• Approximate location: your device's time zone, which the app sends automatically, and the country you live in if you choose one in your profile. We use them only to work out your local date and time (for notifications and daily features) and to suggest which markets to follow; if you have not chosen a country, we estimate it from your time zone. The app never asks for location permission and never collects your precise location.
• Portfolio data you enter: the assets and quantities you track, and, only if you choose to record them, purchase prices and transactions. This exists solely to provide the app's functionality (tracking, charts, gain/loss, AI summaries).
• Exchange connections (optional): if you connect an exchange with a read-only API key, we store that key encrypted and use it only to read your balances.
• Screenshots, images and documents (optional): if you import holdings via screenshot, or attach an image or document to a question in the in-app assistant, the file is sent to an AI provider to be read and is not retained after processing.
• Voice recordings (optional): if you add holdings or ask AIsier a question by speaking, the recording is sent to a speech-to-text provider to be transcribed and is not retained by us afterwards. Only the holdings you confirm, or the question you choose to send, are saved.
• Asset searches: when you search for an asset, the word you type is sent to our market-data providers (Yahoo Finance, CoinGecko) so they can find it. We do not store what you searched for, our logs keep only the length of the query, which is all we need to spot a broken search.
• Chat messages: questions you ask the in-app assistant and its replies are stored so your conversation continues where you left off.
• Feedback you send: if you use the in-app feedback form, we store your message, the category you chose, and your app version and platform, so we can respond and fix the issue.
• Diagnostic logs: when something goes wrong on our servers or the app crashes, we record the technical error, the request path or screen, the app version, the device model and the affected account so we can fix it. If the app itself crashes on your device, a crash report (device model, operating system and app version, the screen and the technical stack trace, never your portfolio or chat content) is also sent to Google Firebase Crashlytics. Passwords and credentials are stripped out before anything is written to a log.
• In-app usage: which screens you open and how long you stay on them, so we can see which parts of the app are useful and which are confusing. We record the screen name and the time spent, a few interaction counts on that screen (how far you scroll, taps that got no response, whether you opened, followed or closed an in-app tip or tour, and how you answered the notification permission prompt: allowed, declined or skipped) and, on the web, page-speed timings (loading, responsiveness and layout-stability numbers) for a sample of visits, never the content of the screen. Your portfolio values, the assets you look at, your chat messages and your searches are not part of this. We do not record your IP address, device identifier or location, and we do not use third-party trackers or advertising SDKs. This data is tied to your account, is included in your data export, and is deleted with your account. Detailed records are removed after 90 days; only anonymous daily totals per screen are kept beyond that.
• Push notification token (optional): if you enable notifications, a device token so we can deliver them. It identifies a device installation, not you personally.
• Purchases: your membership plan and whether it is active, the credit packs you bought, and the transaction identifier from the store you paid through (Apple App Store, Google Play or, on the web, Stripe), so paid features work and no purchase is counted twice. We never see your card details.
• Website visits: this website, aisierinvest.com, runs no analytics scripts and sets no tracking or advertising cookies; the web app stores a single sign-in cookie once you sign in. Its standard access logs (IP address, browser, the page that sent you there, the page you opened and the time) are kept for 90 days; we use them for security and to count how many people visit, from which country and website, and which pages they read (the country is worked out from the IP address and only the totals are kept), never to identify you or to build a profile.

What we do NOT do

• We do not sell your data. Ever.
• We do not share your personal data with third parties for their marketing.
• We do not track you. The app contains no advertising SDKs, no analytics SDKs and no third-party trackers, and we do not track you across other companies' apps or websites.
• We do not hold funds, execute trades, or access exchange withdrawal permissions.
• We do not use your data to train AI models.

AI processing

To generate plain-language summaries, relevant market data and your portfolio composition are processed by AI service providers: Anthropic (Claude) and xAI (Grok), either directly or through Amazon Web Services (Amazon Bedrock). We send only what the feature needs: which assets you hold, their market data, and the questions, screenshots, attached images or documents, or voice transcripts you choose to submit. We never add your account e-mail address, credentials or payment information. Text you type into the assistant is sent as you wrote it, so please leave out personal details you do not want processed. AI outputs are educational summaries, not investment advice.

Service providers we rely on

We use a small number of processors to run the app. They may handle data only on our instructions and for the purpose listed:

How long we keep data

• Account and portfolio data: until you delete your account. Deletion removes it from our live systems immediately and permanently; copies in our database backups are overwritten within 30 days.
• Diagnostic, service and website access logs: automatically deleted after 90 days.
• Internal debugging records: automatically deleted after 30 days.
• Screenshots, chat attachments and voice recordings: not retained, processed and discarded.
• Search terms: never stored.

Storage & security

Data is stored on secured servers; exchange credentials are encrypted at rest. Authentication uses industry-standard tokens. Payments are processed by Apple, Google Play or Stripe; we never see your card details.

Your rights

You can access and update your data in the app, and permanently delete your account and all associated data at any time via Profile → Account → Delete my account, or by e-mailing privacy@aisierinvest.com. Deletion is irreversible and immediate.

Depending on where you live, you may also have the right to request a copy of your data, ask us to correct it, object to or restrict how we use it, or complain to your local data protection authority. Write to privacy@aisierinvest.com and we will respond within 30 days. We will never charge you or degrade your service for exercising these rights.

International transfers

We are a US company and our servers and service providers may be located in the United States and other countries. Wherever your data is processed, the protections described in this policy apply.

Children

Our apps are not directed at children under 13 (or the equivalent minimum age in your region), and we do not knowingly collect data from them. If you believe a child has created an account, write to privacy@aisierinvest.com and we will delete it.

Changes

We may update this policy; material changes will be announced in-app. Continued use after an update constitutes acceptance.
