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. See "Notifications" below.
4. Running counters for the weekly anonymous usage summary — see the "Crash reports and anonymous usage analytics" section below for what these are and what the app does with them.
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. See below.
3. To send a single weekly anonymous usage summary to the developer. See below.
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.
Permissions used for notifications:
- POST_NOTIFICATIONS — required by Android 13 and newer to display a notification. The app prompts you for this permission only when you first opt in.
- RECEIVE_BOOT_COMPLETED — lets the daily check survive a phone restart, so you do not have to open the app to re-arm notifications after a reboot.
- WAKE_LOCK — held briefly (typically a few seconds) while the daily check fetches market data and computes the score. Released as soon as the work is done.
You can turn notifications off at any time from inside the app (Settings → master toggle), or in Android system Settings → Apps → Driptometer → Notifications. Either route stops further notifications immediately and cancels the scheduled daily check.
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, under a data processing agreement, 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. Crashlytics is disabled in development builds and only runs in the version you install from the Play Store.
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 — how many times the app was opened in the past week
- signal_fired — how many warning signals fired across those opens
- tab_signals — how many times the Signals tab was opened
- tab_charts — how many times the Charts tab was opened
- tab_backtest — how many times the Backtest tab was opened
- days_covered — the length of the reporting window in days
All six numbers are aggregated on your device first and reset after the weekly upload. The per-tap and per-open events never leave your device. The weekly_metrics event is the only custom analytics event the app sends.
Alongside this, Firebase Analytics automatically records some standard technical information: a pseudonymous App Instance ID, the app version, the device model, the Android version, the language setting, and the country derived from the IP address (IP itself is not retained). These are used to tell a crash on Android 14 apart from a crash on Android 9, and to spot regional outages — not to identify you.
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, who reads the crash reports and the weekly anonymous summaries.
- Google (Firebase), which acts as a service provider to store and deliver those reports to the developer under Firebase's own privacy terms (https://firebase.google.com/support/privacy).
Firebase is not permitted to use Driptometer data to personalise ads to you.
DOES DRIPTOMETER SHOW ADS?
No. Driptometer is free to use with no advertisements of any kind. The app does not request the Android Advertising ID and does not attempt to profile you for advertising.
A paid "Pro" tier may be introduced in a future release for additional features (for example unlimited history export or score-threshold notifications). The free version will remain free of ads and will not require an account.
DOES DRIPTOMETER USE COOKIES OR TRACKING?
Driptometer does not use cookies or tracking pixels. It does not track you across other apps or websites.
The Firebase services named above use two pseudonymous identifiers to tell one install apart from another: a Firebase Installation ID and a Firebase Analytics App Instance ID. These are generated on your device, are not tied to your Google account, and are not shared with advertisers. You can reset both at any time by going to Settings → Apps → Driptometer → Storage → Clear data, or by uninstalling the app.
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, stops any further crash reports or weekly summaries, and means the old pseudonymous IDs are never reused.
2. Settings → Apps → Driptometer → Storage → Clear data. This resets the App Instance ID and rolls the Installation ID. Any telemetry sent after this point cannot be linked to telemetry sent before it.
3. Email the developer at info@driptometer.com with the subject line "delete my data" and, if you wish, your App Instance ID (visible in the app's About screen). The developer will remove any historical weekly_metrics rows tied to that ID from the Firebase Analytics data retention window.
CHILDREN'S PRIVACY
Driptometer does not knowingly collect any information from children under the age of 13. The app is aimed at adult retail investors. If you believe a child has installed the app and you want to wipe anything sent to the developer, follow the deletion steps above.
DATA RETENTION
Firebase Crashlytics retains crash reports for 90 days by default. Firebase Analytics retains the weekly_metrics events for 14 months by default (the maximum the developer can configure on the free Firebase tier). After those windows the data is deleted automatically by Google.
LEGAL BASIS (UK / EU USERS)
Where UK or EU data protection law applies, Driptometer relies on legitimate interests as the legal basis for processing anonymous crash reports and the weekly anonymous usage summary, because both are necessary to keep the app stable and useful and involve no personal data. You can object to this processing at any time by using any of the three steps in "Your choices and how to delete your data" above.
CHANGES TO THIS POLICY
If this privacy policy changes in the future, the updated version will be posted at this URL with a new "last updated" date. Material changes (for example, adding a new data recipient or a new event) will also be noted in the app's Play Store update description before they take effect.
