1. Scope & the apps it covers
This Privacy Policy applies to the following apps operated by Lulu Ventures LLC ("Lulu Ventures," "we," "us," "our"):
| App | Platform | Distributed as |
|---|---|---|
| Buffett Indicator | iOS | Apple App Store |
| Bubble Watch | Android | Google Play |
Bubble Watch is the Android version of our Buffett Indicator app. The iOS version is distributed as "Buffett Indicator." Both apps provide the same market indicator content and follow the same privacy practices described here. References to "the app" below apply to both.
2. Information we collect
We collect only the information needed to let you sign in and keep your account. Specifically:
- Email address — used to identify your account and to contact you about essential service matters.
- Google Account basic profile — when you sign in with Google, we receive your name, email address, and (if available) your profile picture from Google. We request only the basic profile and email scopes.
- Advertising identifier (Android only) — to show banner ads in the Android app (Bubble Watch), Google AdMob collects your device's advertising ID and standard ad-request signals, and may derive an approximate (city-level) location from your IP address. The iOS app shows no ads and does not collect this. See How we share information.
Apart from the Android advertising data described above, we do not collect your contacts, precise location, photos, device sensors, browsing activity, or any other personal information beyond what is listed above.
3. How we use your information
We use the information we collect only to:
- Create and authenticate your account so you can sign in securely.
- Provide the market indicator content that the app exists to deliver.
- Communicate with you about essential, account-related matters (for example, responding to a support or privacy request).
- Keep the service secure and prevent abuse of accounts.
Except for the Android app's banner ads (sections 4 and 5), we do not use your information for advertising, profiling, or to train any AI or machine-learning models. Your sign-in data — your email and Google profile — is never used for advertising.
4. What we do not do
- Advertising — Android only. The iOS app (Buffett Indicator) contains no ads. The Android app (Bubble Watch) shows Google AdMob banner ads, which use your device's advertising ID — described in How we share information. We run no other ad networks and serve no ads in the iOS app.
- No analytics or crash tracking. We do not collect usage analytics or crash/diagnostic data through third-party SDKs.
- No behavioral tracking by us. We do not track you across other apps or websites, and your sign-in data is never used to profile you.
- No subscriptions or in-app purchases. The apps do not process payments and do not collect billing or payment information.
- No sale of personal data. We never sell your personal data. The only third-party sharing is the Android AdMob advertising described in section 5; you can limit it by resetting or deleting your advertising ID in your device settings.
5. How we share information
We do not sell your personal data. Our apps and your account data are hosted on Google (Firebase) in the United States, which also provides "Sign in with Google" authentication.
Advertising (Android only). The Android app (Bubble Watch) displays banner ads through Google AdMob. To serve them, AdMob collects your device's advertising ID and standard ad-request information, may use an approximate (IP-derived) location, and shares this data with Google for ad delivery and measurement, in accordance with Google's policies (see policies.google.com/technologies/ads). You can reset or limit your advertising ID at any time in your device settings (Settings → Google → Ads). The iOS app (Buffett Indicator) contains no ads and does not collect an advertising ID.
Apart from the hosting, authentication, and Android advertising described above, we do not share your information with anyone else, except when required by law.
6. Data retention
- Account data (your email and Google profile basics) — kept while your account is active, and deleted within 30 days of an account-deletion request.
- Support correspondence — kept only as long as needed to resolve your request and meet our legal obligations.
- Backups — encrypted backup copies are overwritten on a rolling basis, within 90 days.
7. Your rights & choices
No matter where you live, you can:
- Access the personal data we hold about you.
- Correct inaccurate account information.
- Delete your account and associated data (see section 8).
- Withdraw consent at any time where processing is based on consent.
Residents of California, the other US states with comprehensive privacy laws, the EEA, the UK, and Switzerland have additional statutory rights (such as portability and the right to lodge a complaint with a supervisory authority). To exercise any right, email team@deepvalues.ai. We read every request and reply as soon as possible, and you will not be treated differently for exercising a privacy right.
8. Deleting your account & data
You can request deletion of your account and all associated personal data at any time. Email team@deepvalues.ai from the address associated with your account, with the subject "Delete my account." We will permanently delete your email and Google profile data, and confirm once it is done. Deletion is permanent and propagates to backups within 90 days.
9. Security
- Data is encrypted in transit (TLS) and at rest.
- Account sign-in is handled through Google's authentication; we never see or store your Google password.
- Access to stored account data follows the principle of least privilege and is restricted to authorized personnel.
No system is perfectly secure, but we work to protect your information using industry-standard safeguards.
10. Children
The app is rated 4+ on the App Store, meaning its content is suitable for all ages. It is an informational market-indicator tool and is not directed at children as its audience. Signing in requires a Google Account, which Google requires account holders to meet a minimum age for (generally 13, or older in some regions).
We do not knowingly collect personal information from children under 13 (in compliance with COPPA), or under 16 where that is the applicable age of digital consent. If you believe a child has provided us with personal information, email team@deepvalues.ai with the subject "Child data deletion" and we will remove it promptly.
11. Changes & contact
We may update this Privacy Policy to reflect changes in the apps, our practices, or the law. When we make material changes, we will update the "Effective" date above and, where appropriate, provide additional notice. Your continued use of the apps after an update means you accept the revised policy.
For any privacy question, request, or complaint:
- Email: team@deepvalues.ai
