See also our Terms of Use.

Summary

• The App has no account and no login.
• Your birth details and your readings are kept on your device.
• To write a reading, your birth details are sent to our reading service and from there to Amazon Bedrock, which hosts the AI model. They are not stored there.
• The App shows optional rewarded ads from Google AdMob, which uses your device's advertising ID.
• We do not sell your personal data.

1. What we collect, and why

Birth details.The date of birth, birth time (if you know it), sex, and birth city you enter, together with the latitude and longitude of that city, which the App looks up from a list built into it. We need these to calculate your chart. The App does not read your device's location for this or for anything else.

These details are kept on your device. They are sent to our reading service, at api.halallog.com, each time a reading is generated.

Names you type. If you save a chart for another person, any name or label you give it stays on your device only. It is never sent to us.

In-app activity. A record of your fortune balance, which readings you have opened, and basic usage events such as opening the App or unlocking a reading. This is kept on your device, and a copy of the usage events is sent to our analytics provider. These events carry no birth details, no names, and no reading text.

Technical data at our servers. When your device contacts our reading service, our servers see your IP address. We use it only to apply rate limits that keep the service available and to detect abuse. It is held in memory for those limits and appears in short-lived server access logs. It is not linked to your birth details and not used to build a profile.

Advertising data.The App shows optional rewarded ads through the Google Mobile Ads (AdMob) SDK. Through that SDK Google may access your device's advertising ID, your IP address, device information, and information about the ads you see and interact with, under Google's own privacy policy. The App declares the advertising ID permission for this reason.

2. What we do not collect

We do not collect your name, email address, phone number, contacts, photos, camera, microphone, files, precise or device location, health data, or any account credentials. The App has no login. This version has no camera feature and takes no photos.

3. Where your birth details go, and what is kept

Your birth details are sent to our reading service, which calculates the chart and asks an AI model to write the reading. The model is Claude, made by Anthropic, and we run it on Amazon Bedrock, a service of Amazon Web Services, on servers in the United States.

We do not store your birth details on our servers. What we store is the finished reading text, saved under a one-way fingerprint computed from the chart facts, so that the same chart does not have to be paid for and generated twice. That stored text is not linked to you, to your device, or to your IP address, and readings for the same chart are shared between everyone who has that chart.

Our reading service and the AI provider process your birth details on our instructions and for no other purpose. They are not permitted to use them to train models or for their own purposes.

4. Service providers

• Amazon Web Services (Amazon Bedrock), United States. Hosts the AI model that writes your reading. Receives your birth details for that purpose.
• PostHog, United States. Product analytics. Receives anonymous usage events only. No person profile is created and no birth details are sent.
• Google (AdMob). Serves the rewarded ads described in section 1 and processes advertising data under its own privacy policy.

5. Legal bases (for people in the EU, EEA, and UK)

• Providing the reading you asked for: performance of a contract with you (GDPR Article 6(1)(b)).
• Rate limiting, abuse prevention, and keeping the service available: our legitimate interests in operating a secure service (Article 6(1)(f)).
• Anonymous product analytics: our legitimate interests in understanding how the App is used (Article 6(1)(f)).
• Personalised advertising, where it applies: your consent, collected through the consent message shown when you first open the App (Article 6(1)(a)). You can change your choice at any time in the App's settings.

We do not ask you for, and do not want, information about your health, your religion, your politics, or your sexual orientation. Please do not enter any.

6. International transfers

Our reading service and the providers above process data in the United States. For people in the EU, EEA, or UK, these transfers are made under the transfer safeguards those providers offer, which include the European Commission's Standard Contractual Clauses and, where applicable, the EU to US and UK to US Data Privacy Framework. You can ask us for details at the address above.

7. How long we keep things

• On your device: until you delete your chart in the App or uninstall it.
• Generated reading text on our servers: kept so it can be reused, and not linked to you. It is removed when our cache rolls over.
• Server access logs containing IP addresses: a short period for security and troubleshooting, then deleted.
• Analytics events: retained by our analytics provider under its standard retention period.

8. Your rights

Depending on where you live, you have the right to access, correct, delete, or receive a copy of your personal data, to object to or restrict some processing, and to withdraw consent. Because the App has no account, most of your data is only on your device and you can exercise these rights directly:

• Delete.Settings, then “Delete my chart”, removes your birth details, readings, and balance from your device. Uninstalling the App also removes them.
• Advertising.You can reset or delete your advertising ID in your device settings, and you can change your ad consent choice in the App's settings.

For anything else, or if you are in the EU, EEA, or UK and want us to act on a request at our end, write to contact@87lab.app. We will answer within 30 days. You also have the right to complain to your local data protection authority.

If you are a California resident: we do not sell or share your personal information as those terms are defined by California law, and we do not use it for cross-context behavioural advertising without your consent.

9. Children

ILJU is for adults aged 18 or over. It is not directed to children and we do not knowingly collect personal data from anyone under 18. If you believe a child has provided us personal data, write to us and we will delete it.

10. Security

Data sent between the App and our service is encrypted in transit using HTTPS. No method of transmission or storage is completely secure, and we cannot guarantee absolute security.

11. Changes

We may update this policy. When we do, we will change the date at the top. If the change is material, we will tell you in the App.
