Terms of Service

Introduction

Welcome to Keldura. These Terms of Service govern your use of our website and services. By accessing or using Keldura, you agree to be bound by these Terms. Our Privacy Policy explains how we handle personal data.

Who Can Use Keldura

You must be at least 13 years old, or older if the law where you live sets a higher age for using online services on your own. If you are under 18, you need the permission of a parent or guardian, who accepts these Terms on your behalf.

Free Beta

Keldura is in a free beta. During the beta, accounts get more generous features and limits than their plan includes, and both can change as we tune the service. When the beta ends, your account continues on its plan with that plan's limits. We will announce the end date in the app before it arrives. Our beta expectations page has the details.

Use of Services

Keldura provides transcription, translation, summarization, document conversion, content import, folder organization, folder chat, publishing, sharing, analytics, and related AI-assisted services. Eligible users may also connect Telegram bots to selected folders so Telegram chats can ask questions against Keldura content.

You agree to use these services only for lawful purposes and in accordance with these Terms. You are responsible for maintaining the confidentiality of your account information and for all activities that occur under your account, including activities by integrations, Telegram bots, shared links, and published content you configure.

Your Content and Permissions

You are responsible for the URLs, files, recordings, transcripts, prompts, folders, messages, and other content you upload, import, publish, share, or connect to Keldura. You must have the rights and permissions needed to process that content and to permit Keldura and its service providers to use it for the purpose of providing the requested features.

You retain ownership of your content. By using Keldura, you grant Keldura the limited permission needed to host, store, process, transform, index, transmit, display, export, delete, and otherwise operate on your content as required to provide the service.

Keldura uses YouTube API Services to read details about videos, channels and playlists. If you use Keldura with YouTube links, you also agree to the YouTube Terms of Service.

Telegram Bots

If you create or manage a Telegram bot through Keldura, you are responsible for the bot token, BotFather configuration, selected folders and prompts, allowed Telegram users, group-chat settings, webhook or polling mode, and any Telegram chats where the bot is added. You must not connect a bot or process Telegram messages unless you have the authority to do so.

Telegram bot tokens are submitted to Keldura so the service can operate the bot. Do not paste bot tokens into public places, issue comments, support tickets, or other insecure channels. You are responsible for rotating or revoking a token if it is exposed, if BotFather access changes, or if you no longer want Keldura to operate the bot.

AI Outputs

Keldura uses AI and other automated systems to generate transcripts, translations, summaries, answers, citations, titles, and related outputs. AI outputs may be incomplete, inaccurate, or unsuitable for a particular purpose. You are responsible for reviewing outputs before relying on them or sharing them with others.

Acceptable Use

You agree not to use Keldura to:

• violate laws, regulations, intellectual-property rights, privacy rights, or platform rules;
• upload, import, publish, share, or process content you are not allowed to use;
• send spam, abuse, malware, deceptive content, or harmful automation through Keldura or connected Telegram bots;
• attempt to bypass access controls, plan limits, rate limits, security protections, or provider restrictions;
• interfere with the service, scrape it at abusive rates, or use it to attack another service.

Our Acceptable Use page sets out these rules in full and governs if the two differ.

Public Access, Sharing, and Publishing

Some Keldura features may be available to logged-out users when public access is enabled. You are responsible for reviewing what you make public through share links, published folder sites, exports, or Telegram bot group chats. Anyone with access to a public or shared destination may be able to view, copy, or interact with the content exposed there.

Intellectual Property

The Keldura service and its original content, features, and functionality are owned by Keldura and are protected by international copyright, trademark, patent, trade secret, and other intellectual property laws.

Service Changes and Suspension

We may change, limit, suspend, or discontinue features when needed to operate the service, comply with law, protect users or providers, respond to abuse, handle third-party provider changes, or maintain system reliability. We may remove content, disable public access, stop a Telegram bot, or suspend an account when we believe continued operation would violate these Terms or create risk for Keldura, users, or third parties.

Closing Your Account

You can stop using Keldura at any time. To close your account and have your data erased, email hello@keldura.ai from the address on the account. We complete the request within 30 days, as our Privacy Policy describes.

Changes to These Terms

We may update these Terms. We publish the new version on this page with a new effective date and announce significant changes in the app's What's New page. If you keep using Keldura after a new version is published, you accept the updated Terms.

Disclaimers and Liability

Keldura is provided on an "as is" and "as available" basis. We do not guarantee that the service, third-party integrations, AI outputs, imports, exports, Telegram delivery, or generated citations will be uninterrupted, error-free, complete, or accurate. To the maximum extent permitted by law, Keldura and its operator, Yuri Zelikov (sole proprietor), trading as WavelyLabs, are not liable for indirect, incidental, special, consequential, or punitive damages arising from your use of the service.

Plans, billing and payments

When you buy a paid plan or credit pack, your order is processed by our reseller, Polar Software, Inc., which is the merchant of record for all orders and handles payment, tax and invoicing. Each price is shown with its currency on our pricing page. Taxes are calculated at checkout by our reseller, Polar, when paid plans launch.

If you buy a subscription, it renews automatically at the end of each billing period until you cancel. Once paid plans launch, you will be able to change plans from your account, and checkout will show any prorated charge or credit for the rest of the current period before you confirm. We will tell you in advance before a price change applies to your plan. If a payment fails, we may pause paid features until it succeeds.

Credits and monthly allowances work as described on the credit costs page.

Cancellation and refunds

Once paid plans launch, you will be able to cancel any time from your account; a cancelled plan stays active until the end of the period you paid for. Refunds follow our Refund Policy.

Content and rights

You keep ownership of the content you bring in. Only import content you own or have permission to use, and follow our Acceptable Use rules.

Governing law

These Terms are governed by the laws of Israel. Disputes are subject to the competent courts in Tel Aviv, Israel.

Nothing in these Terms limits rights you have under the consumer law that applies to you.

Operator

Keldura is operated by Yuri Zelikov (sole proprietor), trading as WavelyLabs, Tel Aviv, Israel.
