Introduction
Welcome to acha AI.
These Terms of Service ("Terms") govern your use of the acha AI mobile application (the "Service") operated by Retrica, Inc. ("Company", "we", "our", "us").
Our Privacy Policy also governs your use of the Service and explains how we collect, use, and safeguard your information. Your agreement with us includes these Terms and our Privacy Policy (together, the "Agreements").
By using the Service, you acknowledge that you have read and understood the Agreements and agree to be bound by them. If you do not agree, you may not use the Service.
Eligibility
The Service is intended only for individuals at least eighteen (18) years old. By using the Service, you represent and warrant that you are at least 18 years of age. We do not knowingly provide the Service to anyone under 18.
Account
You may browse the Service and explore AI filters without creating an account or logging in.
An account is required only when making a purchase. We offer Apple Login and Google Login and do not request or store any passwords or additional personal information beyond what is necessary. Account creation is solely to ensure the security of your purchased Credits, prevent loss, and enable multi-device access with a single purchase.
You are responsible for maintaining the confidentiality of your account and for all activities that occur under your account. You must notify us immediately upon becoming aware of any unauthorized use.
We reserve the right to terminate accounts at our sole discretion for any violation of these Terms.
Credits System
The Service uses an internal point system called "Credits." Credits are consumed when you use AI features of the Service.
Credits can be obtained through:
(a) Subscription plans, which may include a fixed allocation of Credits per billing period;
(b) One-time purchases of a fixed number of Credits.
Credits are non-transferable, non-refundable (except as required by law), and have no cash value. Unused Credits from one-time purchases do not expire. Credits allocated through subscriptions may be subject to expiration as described at the time of purchase.
We reserve the right to modify the Credit consumption rates for AI features at any time.
Subscriptions
Some features or Credit allocations are available on a subscription basis ("Subscription"). You will be billed in advance on a recurring basis ("Billing Cycle") as determined by the subscription plan you select.
Your Subscription will automatically renew under the conditions set by the Apple App Store or Google Play Store ("App Store"). You may cancel your Subscription at any time through the subscription management settings of the applicable App Store.
We may offer a free trial period ("Free Trial") at our sole discretion. If you do not cancel before the Free Trial ends, you will be automatically charged the applicable Subscription fee. Free trials are limited to once per Apple ID or Google account.
Payments
All payments are processed exclusively through the Apple App Store or Google Play Store. We do not collect or store your payment card details.
We use RevenueCat, Inc. as a third-party subscription management platform to process and manage subscriptions across app stores.
Except as required by law, all purchases and subscription fees are non-refundable.
Fee Changes
We may modify subscription fees or Credit pricing at any time at our sole discretion. Any fee change for subscriptions will become effective at the end of the then-current Billing Cycle. Continued use of the Service after a fee change constitutes your agreement to pay the modified amount.
AI Image Generation
The Service uses artificial intelligence to generate images based on user-provided photos and inputs.
Generated results may vary and may not always accurately represent the input photo. We do not guarantee that generated images will be accurate, complete, or suitable for any particular purpose. Generated images are provided for creative and entertainment purposes and may contain inaccuracies.
User Uploaded Photos
By uploading or selecting photos for use with the Service, you grant the Company a limited, non-exclusive license to process and transform those photos solely for the purpose of generating AI images through the Service.
You represent and warrant that you have the necessary rights and permissions to upload and use such photos.
Facial Data Processing
When you use AI features, photos containing your face ("Facial Data") are transmitted to Google Cloud (Google LLC) for processing. All transmissions are protected by end-to-end encryption.
Your Facial Data is not persistently stored on our servers or on Google Cloud servers. It is processed in volatile (temporary) memory for approximately 20 seconds and automatically purged upon completion.
We do not use Facial Data for identity recognition, biometric identification, or any form of facial recognition outside the functionality required to generate AI images through the Service.
For full details on how we collect, use, share, and retain Facial Data, please refer to our Privacy Policy.

The Service, including but not limited to all AI filters, algorithms, models, user interface designs, graphics, and underlying technology, are and will remain the exclusive property of Retrica, Inc. and its licensors.
