Terms of Service

Last updated:

1. About These Terms

Shiko ("Service") is run by Jarosław Kudzia, Runowska 5b/3, 73-155 Węgorzyno, Poland("we", "us"). You can reach us at support@shiko.app. By using Shiko you agree to these Terms. If you don't agree, please don't use it.

You must be at least 16 years old (or 13 where the GDPR does not apply). If you use Shiko for an organization, you confirm you can accept these Terms for it.

If you are a consumer, the mandatory consumer laws of your country still apply, and nothing in these Terms takes away rights you have under them.

2. The Service

Shiko is a mind mapping app with live collaboration, AI suggestions you ask for, plugins, recipes and export. To use it you need a current browser with JavaScript turned on and an internet connection. Changes made offline are saved when you reconnect.

We may change, suspend or stop parts of Shiko when there is a good reason, such as security, a legal requirement, a technical limit or an improvement. If a change substantially reduces what you paid for, we will tell you at least 30 days ahead where we can, and you can cancel and get a refund for the unused part of your paid period.

3. Accounts

3.1 Creating an Account

You can sign up with email and password, or with Google or GitHub. Give accurate information.

3.2 Your Responsibilities

  • Keep your login details secure
  • Tell us promptly if someone else has used your account
  • You are responsible for what happens under your account

3.3 Guests

You can join a shared map with a room code without an account. Shiko then makes a temporary guest account with the name you enter. Guests have fewer features. A guest account is removed after 90 days without use, sooner if the map owner removes the guest, or if the guest asks us to delete it at support@shiko.app. What a guest added to a map stays there without their name.

4. Plans, Billing & Refunds

4.1 Plans

Shiko has a Free plan and a Pro plan. What each includes and the current prices are on the pricing page. The price you see at checkout, with any tax, is the price you pay.

4.2 Who Sells Pro

Pro is sold by our payment partner, Polar Software, Inc. ("Polar"), as seller of record. You buy from Polar, it takes payment and handles tax and invoices, and Polar's buyer terms apply to the purchase. We never see your card details. For billing problems you can write to us or to Polar.

4.3 Renewal and Cancellation

Pro renews automatically each month or year until you cancel. Cancel any time from Billing in your account settings. You keep Pro until the end of the period you paid for, then your account moves to the Free plan. If you are over the Free limits at that point, you may need to delete content or upgrade to keep adding to it.

4.4 Refunds and Your Right to Withdraw

You can cancel your first Pro purchase within 14 days of your first payment and get a full refund, without giving a reason. Email support@shiko.app or ask Polar. The refund goes back to the way you paid. Later renewals are not refunded unless the law requires it or Shiko failed to provide the service. Your legal rights as a consumer are not affected.

4.5 Price Changes

If we raise the price of Pro, we will tell you at least 30 days before it applies to your next renewal, and you can cancel before then.

5. Acceptable Use

Don't use Shiko to:

  • Create, store or share illegal content
  • Share content that infringes others' rights, or that is defamatory, harassing, threatening, or promotes violence or discrimination
  • Distribute malware or take part in phishing, fraud or deception
  • Get into other people's accounts or data
  • Disrupt Shiko, scrape it or use bots on it without permission, or get around limits or billing
  • Resell or commercially exploit Shiko without our agreement

We limit how fast Shiko can be used so it stays stable for everyone. Heavy use that affects other people or our systems may be slowed or restricted.

6. Your Content

6.1 You Own It

You keep ownership of everything you create in Shiko ("your content"). We don't claim it.

6.2 Licence to Shiko

You give us a limited, worldwide, non-exclusive, royalty-free licence to store your content, show it to you and the people you share it with, process it to provide the Service (including AI features you ask for), and keep backups. The licence ends when you delete the content or your account, except for backups, which are overwritten within 90 days, and for what you added to other people's maps, which stays there without your name (see section 12).

6.3 Your Responsibility

You are responsible for your content and for having the right to use it, including when you use AI features on text other people wrote. See our Privacy Policy for what AI features send.

6.4 Removing Content

We may remove or hide content that breaks these Terms or the law. We tell you why and how to object, unless the law stops us. See section 9.

7. Plugins & Recipes

7.1 Using Them

A map's owner can turn plugins on for it. Shiko reviews the plugins it offers and runs them in a restricted sandbox in your browser, but plugins are made by their authors, and section 11 applies to them too. The Privacy Policy explains what a plugin that connects to a site sends.

7.2 Publishing Them

If you submit a plugin or share a recipe, you confirm that:

  • You have the right to publish it
  • A plugin does what it says, reaches only the sites it names, and contains no malware or code meant to collect people's data

You give other Shiko users a licence to run your plugin or copy your shared recipe, and we may show your display name as the author. We may review, refuse, publish or turn off a plugin or recipe, and we tell you why. If you delete your account, your plugins are removed; copies of a recipe that people already installed stay with them.

8. AI Features

  • AI output can be wrong, incomplete or unsuitable. You are responsible for checking it before you rely on it.
  • AI features send our AI provider what the result needs (node text and tags, how nodes connect, the map's title and description, and what you type for AI); the Privacy Policy has the details.
  • AI features can be unavailable or change when the models behind them change.
  • Don't use AI features to break section 5, to copy or extract the AI models, or to create content meant to deceive people.

9. Reporting Illegal Content

9.1 How to Report

If you see illegal content on Shiko, or a plugin that misbehaves, tell us. For content, email support@shiko.app with where it is (a link to the map is best), why you think it is illegal, and your name and email. For a plugin, use Report in its menu.

9.2 What We Do

We review reports promptly and may remove or disable the content, or turn a plugin off (we then tell the owners of the maps that use it). We tell the person who posted it what we did and why, and they can reply to us and ask us to look again.

9.3 Contact Point

This email is also our single point of contact for authorities and for anyone using Shiko under the EU Digital Services Act. Write in English or Polish.

10. Third-Party Services

Shiko links to or works with other services, such as Google and GitHub sign-in and the sites some plugins connect to. They have their own terms and privacy policies, and we are not responsible for what they do.

11. Warranties & Liability

11.1 No Promise of Perfection

TO THE EXTENT THE LAW ALLOWS, SHIKO IS PROVIDED "AS IS" AND "AS AVAILABLE", WITHOUT WARRANTIES THAT IT WILL BE UNINTERRUPTED, ERROR-FREE, OR SUITED TO YOUR PARTICULAR NEEDS.

11.2 Limit on Liability

TO THE EXTENT THE LAW ALLOWS, WE ARE NOT LIABLE FOR INDIRECT OR CONSEQUENTIAL LOSS, OR FOR LOST PROFIT, REVENUE OR DATA, AND OUR TOTAL LIABILITY FOR ANY CLAIM IS LIMITED TO WHAT YOU PAID US IN THE TWELVE MONTHS BEFORE THE CLAIM, OR $100 IF THAT IS MORE.

11.3 What This Does Not Limit

Nothing in these Terms limits liability that cannot be limited by law. That includes liability for intent or gross negligence, for injury to a person, and, for consumers, rights the law gives you, such as the right to a service that matches what was promised.

11.4 Business Users

If you use Shiko for business, you will cover claims from third parties that arise from your content or your breach of these Terms.

12. Ending Your Account

12.1 By You

You can delete your account in your account settings or by emailing us. Deleting it cancels Pro straight away and does not refund the rest of the period, so cancel Pro first if you want to use the time you paid for. Export your data first if you want to keep it. Your maps are deleted. What you added to other people's maps stays there without your name, so delete items first if you want them gone. The Privacy Policy has the details.

12.2 By Us

We may suspend or end your account if you break these Terms, if your use is a security risk, if the law requires it, or if we stop offering Shiko. We tell you why and give notice, except where the situation is urgent or the law stops us. If we end a paid account and you did not break these Terms, we refund the unused part of the period.

12.3 After It Ends

Your access stops, your account and maps are deleted, and what you added to other people's maps stays there as "Former member", as the Privacy Policy describes. Sections that by their nature should continue, such as 11, keep applying.

13. Complaints & Disputes

13.1 Complaints

If something is wrong, email support@shiko.app. We answer within 14 days. You can also ask a consumer protection body in your country for help, and you can always go to court.

13.2 Governing Law

Polish law governs these Terms. If you are a consumer, you keep the protection of the mandatory laws of your country of residence.

13.3 Courts

Disputes go to the courts of Poland. If you are a consumer, you can also bring a case in the courts of your own country.

14. Changes to These Terms

For a material change we give at least 30 days' notice by email or in the app, and update the date at the top. If you keep using Shiko after the change takes effect, you accept it. If you disagree, you can delete your account, or cancel Pro for a refund of the unused period, before then.

15. General

  • These Terms, the Privacy Policy and, for Pro purchases, Polar's buyer terms are the whole agreement between us.
  • If a part of these Terms cannot be enforced, the rest still applies.
  • If we don't enforce something straight away, we haven't given it up.
  • You can't transfer your rights under these Terms without our written consent. We may transfer ours to a successor to Shiko, as long as your rights don't get worse.
  • "Shiko" and its logo are our trademarks. The Service's design and code are ours or our licensors'; don't copy or reverse engineer them except where the law allows.
  • If you send us feedback, we may use it without obligation to you.
