PRIVACY POLICY — DRIPTOMETER
Last updated: May 2026

OVERVIEW

Driptometer is a stock market risk indicator app. This privacy policy explains what data the app collects, stores, and uses.

The short version: Driptometer does not ask for your name, email, phone number, or any other personal information. There are no adverts, no accounts, and nothing about you is sold or shared with advertisers. The app does send anonymous crash reports and a weekly anonymous usage summary to the developer so bugs can be fixed and the most-used features can be improved. Details are below.

WHAT DATA DOES DRIPTOMETER COLLECT?

Driptometer does not collect any personal data. The app does not require you to create an account, provide an email address, or share any personal information. It cannot see your name, your contacts, your photos, your location, or anything else outside its own storage.

WHAT DATA IS STORED ON YOUR DEVICE?

Driptometer stores a small number of items locally on your device only:

  • 1. Your 90-day risk score history — a list of daily scores used to draw the history chart. This never leaves your device.
  • 2. Whether you have seen the welcome screen — a single true/false value so the app does not show the introduction every time you open it.
  • 3. Your notification preferences (if you opt in) — the master toggle, the six per-direction toggles, the quiet-hours window, and a record of which risk level was last announced. None of this leaves your device.
  • 4. Running counters for the weekly anonymous usage summary — see the "Crash reports and anonymous usage analytics" section below.

All of these are stored using Android's standard local storage. Items 1, 2, and 3 are never transmitted anywhere.

DOES DRIPTOMETER ACCESS THE INTERNET?

Yes, for three reasons:

  • 1. To fetch publicly available financial market data (stock prices, index values, and volatility measures). This data is used solely to calculate the risk score displayed in the app. No personal information is transmitted during these requests.
  • 2. To send anonymous crash reports if the app crashes or hits an unexpected error.
  • 3. To send a single weekly anonymous usage summary to the developer.

None of these requests contain your name, email, account details, or any identifier you gave us, because you never gave us any.

NOTIFICATIONS

Driptometer can send you a notification when its risk level changes between Clear Skies, Partly Cloudy, and Storm Clouds. Notifications are entirely optional, off by default, and never appear unless you opt in.

How notifications work, in plain English:

  • The app schedules a once-a-day check on your device using Android's WorkManager.
  • That check fetches the same publicly available market data the app already uses, recalculates the risk score on your device, and compares the new risk level to the last one it announced.
  • If — and only if — the level has actually changed, a notification is shown by Android on your device.

What the app does NOT do:

  • The app does NOT use Firebase Cloud Messaging (FCM) or any other push-notification service.
  • The app does NOT register or store any push token.
  • The app does NOT send your risk score, your level, your transitions, your toggle settings, or any notification activity to a server. There is no server.
  • A third party cannot trigger a Driptometer notification. Only the on-device daily check can.

CRASH REPORTS AND ANONYMOUS USAGE ANALYTICS

Driptometer uses two services provided by Google's Firebase platform to keep the app stable and to understand which features matter. These services act as service providers — they process data on the developer's behalf and do not use it for their own advertising purposes.

Firebase Crashlytics: If the app crashes, Crashlytics automatically sends the developer a report that includes the error, the stack trace, the app version, the Android version, and the device model. It does not include anything you typed into the app or any ticker you viewed.

Firebase Analytics: At most once every seven days, the app sends a single anonymous event called weekly_metrics. The event contains six numbers: app_opened, signal_fired, tab_signals, tab_charts, tab_backtest, and days_covered. All six numbers are aggregated on your device first and reset after the weekly upload.

DOES DRIPTOMETER SHARE DATA WITH THIRD PARTIES?

No. Driptometer does not sell or share data with third parties such as advertising networks, data brokers, or other app companies. The only parties who see the data in the sections above are the developer and Google (Firebase), which acts as a service provider.

YOUR CHOICES AND HOW TO DELETE YOUR DATA

You have three ways to stop the app collecting anything more about your device, or to clear data already sent:

  1. Uninstall the app. This wipes all on-device data.
  2. Settings → Apps → Driptometer → Storage → Clear data. This resets the App Instance ID.
  3. Email the developer at info@driptometer.com with the subject line "delete my data".
This privacy policy applies to the Driptometer Android application. Contact: info@driptometer.com.

What is a Stock, Really?

📋 Driptometer Blog Post Post #002 | Topic: What is a Stock, Really? What is a Stock, Really? A Plain English Guide to Stock Market Basics Published: May 21, 2026 | Category: Investing for Beginners When you hear people talk about the stock market, the word "stock" gets thrown around constantly. But if you are trying to learn stock market basics , you need to understand what a stock actually represents. It is not just a flashing digital ticker symbol or a line on a complicated chart; it represents real-world ownership. The Core Concept: Tiny Pieces of a Business When you engage in buying shares of a company, you are purchasing a fractional piece of ownership in that business. If a corporation has one million total shares outstanding, and you buy exactly one share, you legally own one-millionth of that entire company. This makes you a shareholder. Whether it is a tech giant or an international coffee chain, owning their stock means you own a tiny slice of their ...
