These terms are an agreement between you and REPECH (“we”) for the Qarta Chrome extension, its optional Qarta Pro subscription and the Qarta website. By installing or using Qarta you agree to them. If the English and Japanese versions differ, the Japanese version prevails.
1. The service
Qarta saves prompts and inserts them into ChatGPT, Gemini, Copilot (personal), Claude, Perplexity and Grok, and keeps a searchable library of the AI chats you open, stored in your own browser. The Free plan works on every supported site, stores up to 10 prompts and 3 chat folders, covers all of your chats in the library, includes the whole job template collection, and can back your prompts up to a file and restore them. Qarta Pro removes the 10-prompt and folder limits, adds sending one prompt to several sites at once, {{variable}} fill-in, pinning and Markdown export, and the other features described in Qarta and on our website.
Qarta is an independent product. It is not affiliated with, endorsed or sponsored by OpenAI, Anthropic, Google, Microsoft, Perplexity or xAI. ChatGPT, Gemini, Copilot (personal), Claude, Perplexity and Grok are trademarks of their respective owners.
2. Qarta Pro subscription, renewal and cancellation
Qarta Pro costs $10 per month or $96 per year (US dollars), charged through Stripe via ExtensionPay when you subscribe. Subscriptions renew automatically at the end of each month or year until you cancel. You can cancel anytime from “Manage billing” in Qarta's side panel or from the customer-portal link in your Stripe receipt email; Qarta Pro stays active until the end of the period you already paid for.
All payments are final and non-refundable for any reason, including cancellation part-way through a period, except where a refund is required by applicable law. Temporary malfunctions — for example while an AI site changes its pages and before we update Qarta — are not grounds for a refund. If we change the price, we'll announce it at least 30 days in advance and it will apply from your next renewal. If we discontinue Qarta Pro, we'll announce it in advance and stop future renewals.
Minors need a parent or guardian's consent to subscribe.
3. Your content and your use of AI services
Your prompts are stored in your Chrome Sync storage and your chat library only in your own browser — not on our servers — and you own everything you save. Because it lives in your browser, it can be lost if you uninstall Qarta, clear browser data or change computers; export backups of anything important. You are responsible for what you save and send, and for following the terms of each AI service you use with Qarta. We don't control and aren't responsible for those services or the answers they give.
4. Acceptable use
Don't reverse-engineer, resell or redistribute Qarta; don't circumvent the Free plan's limits or the Qarta Pro paywall; don't abuse payments (for example fraudulent chargebacks) or send spam or automated requests to our contact form; and don't use Qarta to break any law or anyone else's rights.
If we find a violation, we may suspend or end your access (including Qarta Pro) without prior notice and without refund, and we will take legal action where appropriate, including claims for damages and reports to the police or other authorities. You are responsible for any loss your violation causes us or others, including reasonable legal fees.
5. Changes to Qarta
AI sites change their pages often, and a feature may stop working until we update Qarta. We may improve, change or discontinue features, and will give notice of important changes in Qarta or on our website.
6. No warranty and limitation of liability
Qarta is provided as-is. We don't warrant that it fits any particular purpose, is accurate or useful, is free of errors, or will be available without interruption.
Except in cases of our intentional misconduct or gross negligence, we are not liable for any damage arising from Qarta.
If we are nevertheless held liable under Japan's Consumer Contract Act or other applicable law — and except in cases of our intentional misconduct or gross negligence — our liability is limited to ordinary, direct damage you actually suffered, up to the amount of your most recent single payment to us (zero for Free plan users).
7. Changes to these terms, law and disputes
We may update these terms; the date at the top shows the latest version, and important changes will be announced in advance on this page. Continued use after a change means you accept it. These terms are governed by the laws of Japan, and the district court with jurisdiction over the operator's location has exclusive jurisdiction in the first instance, without limiting any mandatory rights you have as a consumer where you live. If any part of these terms is found invalid, the rest remains in effect. Contact: info@repech.com.
