OracleWorld

Privacy Policy

Effective November 14, 2026. This policy covers the OracleWorld Android app (package com.oracleworld.app) and the OracleWorld website.

The short version

OracleWorld has no user accounts, no ads, no analytics or tracking SDKs, and does not sell or share personal data. We keep only what is needed to confirm your subscription.

What we collect

• Subscription record. When you subscribe, Google Play gives the app a purchase token. Our server sends it to Google to confirm the subscription is active, then stores a one-way hash of the token with its status and renewal date. We never receive your name, email address or payment card. Google handles all payments.
• Session cookie. A signed cookie stores your access status and when it expires, so you don't have to re-verify on every screen.
• Search inputs. If you trace a crypto address or transaction hash, the server forwards it to public blockchain data providers (for example mempool.space, Blockstream and Blockscout) to fetch results. We don't save these searches.
• Technical logs. Our server and hosting provider may briefly keep standard request logs (IP address, time and page requested) for security and troubleshooting. Error logs are deleted within 30 days.

What Google collects

Purchases go through Google Play Billing and are covered by the Google Privacy Policy. The app runs in a Trusted Web Activity, so the browser on your device (usually Chrome) handles cookies and storage under its own settings.

How we use data

We use this data only to provide the service, confirm your subscription and keep the service secure. We do not use it for advertising or profiling.

Sharing

We share data only with Google, to verify purchases, and with our hosting provider, which runs the server. We don't sell personal data.

Retention and deletion

Subscription records are kept while your subscription is active and for up to 12 months afterwards for accounting and fraud prevention, then deleted. To delete your data, clear OracleWorld's site data in your browser settings or uninstall the app. You can also email us and we'll delete any subscription record linked to your purchase.

Children

OracleWorld is a financial-information app for adults. It is not directed at children under 13, and we don't knowingly collect their data.

Security

All traffic is encrypted with HTTPS. Purchase tokens are stored only as one-way hashes, and session cookies are signed and HTTP-only.

Not investment advice

OracleWorld provides information only. Read the Terms & disclaimer.
