Privacy Policy

Last updated: October 28, 2026

The REPLA team ("we") respects the privacy of people who use the REPLA app (the "App") and handles personal and usage information as described below. The Japanese version of this policy is the original; this English version is a translation.

1. Information we collect

1.1 Device identifier

On first launch the App creates a random identifier on your device (Device ID, UUID v4). It is stored on the device and sent to our API server (Cloudflare Workers). It does not identify you personally.

1.2 Questions and conversations

The questions you send to REPLA, the AI's answers, and the conversation ID. They are sent through Cloudflare Workers to Dify Cloud (cloud.dify.ai) to generate the answer.

1.3 Subscription information

Purchase transaction tokens, purchase status and product IDs, through RevenueCat. We never receive your card number or raw payment details.

1.4 Information collected automatically

App version, OS and device model (through the store SDKs)
IP address and user agent of API requests (kept temporarily in Cloudflare logs)

1.5 "My reptiles" records and photos

Records of your animals (name, species, weight, temperatures, feedings, etc.) and their photos are stored only on your device and are not sent to our servers. When you ask a question from an animal's page, its species, life stage, weight, temperatures and last feeding are added to the question text and sent as in 1.2.

1.6 Feedback and inquiries

When you use "Send feedback" in the App, we send the message, the email address you choose to enter (optional), the app version, device type (iOS / Android), OS version and app language to the RAIXEN support desk (hosted on Cloudflare). We use Google's AI (Gemini API) to sort messages, and reply by email from info@raixen.net when a reply is needed. Messages are deleted automatically 180 days after we receive them.

2. How we use information

To generate and show AI answers
To apply usage limits (free plan) and prevent abuse
