Privacy Policy

Information we collect

Account information. If you create an account, we collect the email address and display name you provide, via Firebase Authentication. We use this to identify your account, verify your email, and secure access to your saved reports and backtests.

Report and backtest history. When you generate a report or run a backtest, we save it to your account (ticker, report type, result summary, and the date) so you can view it again later from "My Reports" / "My Backtests". Saved backtests are automatically deleted after 30 days.

Technical and usage data. To keep the service reliable and prevent abuse, we log request metadata including IP address and request timestamps. This is used only for rate-limiting and is not linked to your account beyond what's needed to enforce usage limits.

App integrity verification. The app uses Firebase App Check to verify that requests come from a genuine copy of this app, not a script impersonating it. This does not identify you personally — it verifies the app installation, not the user.

Advertising

The iPhone, iPad and Android apps are free and ad-supported. Advertising is served by Unity LevelPlay (Unity Technologies, formerly ironSource), which mediates between several advertising networks and chooses which one fills each slot. Unity and those mediated networks may collect device identifiers (including your advertising identifier), general device and app-interaction data, and approximate location, and use them to serve, measure and personalise advertising. That data is processed by Unity and its partners under their own privacy policies, not by us.

Some advertising is rewarded: you may choose to watch a short video to reduce the waiting period before your next report. Watching is always optional and nothing is withheld if you decline — the wait simply elapses on its own.

You control ad personalisation from your device. On iPhone and iPad, Settings → Privacy & Security → Tracking, and the App Tracking Transparency prompt shown on first launch. On Android, Settings → Privacy → Ads. Declining tracking does not stop you seeing ads; it makes them less personalised.

Subscribers on any paid plan see no advertising at all, and no ad network SDK requests are made for those accounts.

What we do NOT collect

• We do not access your device's camera, microphone, contacts, or photo library.
• We do not sell your data, and we do not share it with third parties beyond what's needed to operate the app and serve ads (see above).
• We do not collect financial account information, payment card details, or brokerage credentials — this app does not connect to any trading account and cannot place trades.

Third-party services

We use the following services to operate the app; each processes data under its own privacy policy:

• Firebase (Google) — authentication and data storage.
• Google Cloud Run — hosts the backend that generates reports.
• Unity LevelPlay (Unity Technologies) — serves in-app advertising and its mediated ad networks (see "Advertising" above).
• Paddle.com — merchant of record for website subscriptions; processes payment details, billing address and tax location. We never see or store your card details.
• Yahoo Finance — source of market price and fundamentals data (no personal data is sent to this source).

Data retention and deletion

Report history is retained for 7 days. Backtest history is retained for 30 days. Account information is retained until you delete your account.

You can delete your account at any time from Account → Danger zone. This permanently and immediately removes your account and all associated data (saved reports, saved backtests, and your profile) — there is no recovery period, so make sure before confirming.

Your choices

You can sign out at any time from the Account menu, or permanently delete your account and data from Account → Danger zone. Questions about your data outside of that: admin@cloudstoneterminal.caribbeandynetics.com.

Changes to this policy

We'll update this page if what we collect changes — for example if we change advertising provider or add a new processor. The page is updated before the change reaches the app or the website, and the date at the top reflects the last revision.
