RdvGo

Privacy Policy

Effective date: September 21, 2026 · Storetag Corp ("Storetag", "we", "us"), a New Jersey corporation, publishes mobile apps and online services under the RdvGo brand. This policy covers the apps and services listed in Section 11 ("Covered apps").

We collect only what each app needs to work, we explain it in plain language, and you can delete your data yourself. This policy is organized in two parts: the rules that apply to every RdvGo app, and a short section for each app that says exactly what that app collects.

1. Data we collect across all apps

We do not collect precise device location, contacts, photos, health data, or payment card numbers unless an app's section below says so. Payments, where offered, are processed by Apple, Google, or a payment provider; we receive only a receipt.

2. How we use data

We do not sell your personal information. We do not use the personal details you enter into an app for advertising, and we never share them with advertisers.

3. Service providers

Providers receive only the data needed for their purpose and may not use it for anything else on our behalf. Google may use the advertising identifier for ad measurement and, with your consent, personalized ads. You can limit ad tracking in your device settings (iOS: Settings → Privacy & Security → Tracking; Android: Settings → Google → Ads).

4. Retention and deletion

5. Your choices and rights

California residents (CCPA/CPRA)

You have the right to know what personal information we collect, to delete it, to correct it, and to not be discriminated against for exercising these rights. We do not sell personal information. Ad networks may process your advertising identifier while ads are shown in our ad-supported apps, which may count as "sharing" under the CPRA; you can opt out in the app under Me → Ad privacy choices (where offered) or in your device settings. To exercise your rights, use the in-app tools or email us.

European Economic Area and United Kingdom

Our legal bases are performance of our contract with you (providing the service), your consent (notifications, personalized ads), and our legitimate interests (security, fraud prevention, product improvement). You have the rights of access, rectification, erasure, restriction, portability, and objection, and the right to complain to your supervisory authority. Where ads are personalized we ask for consent through Google's consent form in the app.

Other U.S. states

Residents of states with privacy laws (such as Virginia, Colorado, Connecticut, Utah, Texas, and Oregon) have similar rights of access, correction, deletion, and opting out of targeted advertising. Use the same in-app tools or email us.

6. Children

Our apps are not intended for children under 14 unless an app's section below says otherwise, and we do not knowingly collect personal information from them. If you believe a child has provided us data, contact us and we will delete it.

7. Security

Data is encrypted in transit (HTTPS) and stored on access-controlled servers. Sign-in is handled by Firebase, so we never see your password. No system is perfectly secure; please use a strong, unique password if you sign in with email.

8. International users

If you use our apps outside the United States, your data is transferred to and processed in the United States, where privacy laws may differ from your country's. We use standard safeguards for transfers where required.

9. Changes to this policy

If we make meaningful changes we will show a notice in the affected app and update the effective date above. Continued use after the change means you accept the updated policy.

11. Covered apps and app-specific details

K Fortune Teller (Four Pillars)

K Fortune Teller turns your birth date, time, and place into personality, timing, and relationship insights based on the traditional Four Pillars (Saju / BaZi) system. Readings are produced by fixed rules and pre-written text. They are for reflection and entertainment only, not medical, legal, financial, or psychological advice, and they do not predict the future.

DataWhy
