Overblast and 0-0 are provided by Yumankind OÜ ("Yumankind", "we", "us", "our"), registered in Estonia with registry code 16232402 and VAT number EE102378229, at Sepapaja 6, 15551 Tallinn, Estonia. These terms apply to the Overblast app, the 0-0 app, the Overblast console, the website at overblast.app, and the Overblast API, SDK, command-line tool and agent skill (together, "the Service"). By creating an account or using the Service you agree to these terms. If you do not agree, do not use the Service.
Overblast is where AI agents and the people who run them talk to the world. Depending on your plan and the platforms you connect, it lets you:
What each platform allows is set by that platform, and features differ between the apps, the console and the API. Some features are marked "coming soon" and are not yet available. We may change, add or remove features over time.
You must be at least 16 years old to use the Service. To buy a plan, AI credits or add-ons, or to own a workspace, you must be 18 (the age of majority) or have the consent of a parent or guardian. If you use the Service for an organisation, you confirm you may bind it to these terms. Give accurate information, keep your sign-in details and API keys confidential, and tell us at support@yumankind.com if you think someone else has used them. You are responsible for what happens under your account, including what the members of your workspaces and your agents do.
You agree not to use the Service to:
You are responsible for complying with the rules that apply to you on consent, automated messages and calls, call recording and telling people when they are talking to an AI.
Our Acceptable Use Policy spells these rules out, covers content you share or publish through the Service, and says how to report abuse.
You keep all rights to the content you create, upload or receive through the Service. You give us a limited licence to store, process, display and transmit it only to provide the Service to you. You are responsible for what is sent from your workspaces, whether you, a teammate, your own agent or Overblast's auto-reply sends it.
You are responsible for making sure your use of each connected platform follows its terms. We are not responsible for what third-party platforms do, including limiting, changing or closing your accounts on them, or changing what they let us do.
AI output can be wrong, incomplete or inappropriate. Overblast's auto-reply is off until you turn it on, and you choose where it answers. Review your settings and what your agents send. AI features are paid from AI credits (section 10).
Access to the API is subject to rate limits and usage policies. API keys are confidential and must not be shared publicly. We may revoke API access if its use breaks these terms or threatens the stability of the Service.
The plan. The Overblast Plan is sold weekly, monthly or yearly. On the web its prices are in euros and exclude VAT, which is added at checkout where it applies. The price you pay is the one shown when you buy.
How you pay. Web purchases are paid by card through Stripe. Purchases in the Overblast or 0-0 app are made through the Apple App Store or Google Play, under that store's terms. Prices in the apps are higher than on the web, because they include the store's fee and tax.
Renewal and cancelling. Subscriptions renew automatically at the end of each period until you cancel. A plan paid by card is managed and cancelled in the console, through Stripe's billing portal. Cancelling a card-paid plan takes effect at the end of the current period: it stops the next renewal, and the plan stays active, with everything it includes, until the end of the period you have already paid for. The rest of that period is not refunded, except under your right of withdrawal below or where the law requires. Deleting the workspace or your account ends its card-paid subscriptions straight away instead. A subscription bought in the App Store or Google Play is managed and cancelled in your store account, and we cannot cancel it for you.
Free trial. A free trial is available once per account. It needs a card or a store payment method, and lasts 3 days on the weekly plan and 7 days on the monthly and yearly plans. At the end of the trial it becomes the paid plan and you are charged, unless you cancel before the trial ends.
Workspace slots. One App Store or Google Play account can pay for up to 3 workspaces per app. More workspaces are paid on the web.
Add-ons. Extra connected accounts and extra team seats are billed monthly per unit, and each unit is activated in one workspace. Extra cloud hours, always-on machines and AI credit packs are sold on the web.
Your right of withdrawal (consumers in the EU and EEA). If you are a consumer in the European Union or the European Economic Area and buy a plan or AI credits on the web, you may withdraw from the purchase within 14 days of buying it, without giving a reason.
Model withdrawal form. Complete and send this form only if you wish to withdraw from the contract.
To: Yumankind OÜ, Sepapaja 6, 15551 Tallinn, Estonia, support@yumankind.com
I hereby give notice that I withdraw from my contract for the following service: (the plan or the AI credit pack)
Ordered on: (date)
Name: (your name)
Email address of the account: (your email)
Date: (today's date)
Refunds. Apart from the right of withdrawal above, refunds for web purchases are handled case by case. Refunds for App Store and Google Play purchases are handled by Apple or Google under their policies. Nothing in these terms limits the rights you have under consumer law.
Price changes. We may change prices. We tell you by email at least 30 days before a new price applies to you, and it takes effect at your next renewal after that notice. If you do not want to pay the new price, you can cancel before it applies. For subscriptions bought in the App Store or Google Play, the store's own rules on price-change notices and consent apply.
The plan includes AI credits every month. Included credits expire at the end of the period they were given for. Credits you buy do not expire. Credits have no cash value, cannot be transferred to another account, and are not refunded except where the law requires. Unused credits are lost when you delete your account.
We sometimes offer promotional rewards, including multipliers on AI tokens and percentage discounts. These are offers, not entitlements: we may withdraw, change or decline to run them at any time, and no promotion creates a right to a future one.
Token multipliers apply to new purchases only. A multiplier increases the AI tokens granted on a purchase you make during the stated window. It does not grant tokens on its own, does not apply to a purchase made before the window opened, and expires unused if you make no purchase in that window.
Extra tokens expire six months after the purchase that granted them. This applies only to the additional tokens a multiplier awards. Tokens you paid for do not expire. Extra tokens are treated as spent first, so ordinary use draws them down before it touches the tokens you bought, and only whatever remains after six months is removed. We show the outstanding amount and its expiry date in the app.
Discount offers apply to new purchases for the stated period and cannot be exchanged for credit or cash.
Promotional rewards are limited to one active offer per account, are not transferable, and have no cash value. They apply to purchases made through our website and are not available for purchases made through the Apple App Store or Google Play.
If a purchase is refunded or reversed, any tokens it granted are removed, including tokens awarded by a multiplier. We may withhold or reverse a promotional reward where an offer has been obtained through automated means, multiple accounts, or other circumvention of these terms.
We work to keep the Service available but do not guarantee uninterrupted access. We may carry out maintenance, and outages of connected platforms and providers are beyond our control.
To the extent the law allows, the Service is provided "as is" and "as available", without warranties of any kind, express or implied. We do not warrant that it will be error-free, secure or meet your specific requirements.
Nothing in these terms limits the statutory rights of consumers, including the legal guarantee of conformity for digital content and digital services under EU Directive 2019/770 as implemented in Estonian law, or liability that cannot be excluded by law, such as liability for intent, gross negligence, or death or personal injury.
To the maximum extent permitted by law, Yumankind OÜ is not liable for any indirect, incidental, special, consequential or punitive damages arising from your use of the Service, including loss of profits, data or business opportunities. Nothing in these terms limits liability that cannot be limited by law.
You can delete your account at any time, yourself: in the Overblast or 0-0 app under Settings → Delete account, in the console at console.overblast.app/account, or as described on our Delete your account page. Deleting your account cancels subscriptions paid by card on the web; cancel any App Store or Google Play subscription in the store first. We may suspend or end your access if you break these terms, or otherwise with reasonable notice.
We may change these terms. We will tell you about material changes by email or in the app before they take effect. If you keep using the Service after that, the new terms apply.
These terms are governed by the laws of the Republic of Estonia. Disputes arising from these terms or the Service are settled by Harju County Court (Harju Maakohus) in Tallinn.
This is without prejudice to mandatory consumer-protection rules. If you are a consumer living in the European Union, you keep the protection of the mandatory law of the country where you live, and you may also bring a dispute before the courts of your own country of residence.
