These Terms are the rules for using CosCheck: your account, your content, CosCheck Pro and tips, and what happens if the Community Rules are broken. CosCheck is developed and operated by Angeroku, an individual developer based in Latvia ("we", "us").
Keep your login details to yourself; you are responsible for what happens under your account. CosCheck is not intended for children under 13 (or the minimum age that applies where you live).
You keep ownership of everything you create in CosCheck: checklists, notes, photos, voice recordings, comments and trips. When you put content into a shared space (Global Checklists, Co-op Groups including their chat, voice messages, polls, Notes and Photos, a costume you link to a group, or a trip you share with your groups), you allow the other participants to see it, and us to store and display it as needed to run that feature, for as long as it stays in that shared space. Only share photos you have the right to share.
Content in shared spaces (Global Checklists and Co-op Groups, including group chat, voice messages, polls, Notes, Photos and names) must follow these rules, which are also shown in the app under Global Checklists → Rules:
Content that breaks these rules may be removed - a group's captain can also delete photos in their group - and repeat violations can restrict or suspend your account. You can report and block other users in the app.
What Pro includes. CosCheck Pro is an optional subscription, billed monthly or yearly. It currently adds unlimited costumes, up to 150 photos per costume with higher-quality uploads, voice notes in costumes up to 10 minutes long (up to 1 minute without Pro), My Cosplay Recap, Media Kit export, the "What's in which bag" PDF, custom bags, item weights and packing suggestions, plugs and voltage advice for trips abroad, "Travelling together" in groups (who is on your flight, bag weights and spare kg), Creative mode extras (marker, all colours and sizes, body silhouettes, drawing over photos, more pages, high-quality images, handwriting to text), Pro achievements, and the cat companion with its own name and colour (including cats in groups you captain). Some group features work for the whole group when any member has Pro. Features may change over time.
Always free. Co-op Groups (GroupsCos), their chat, voice messages, polls and photos, Global Checklists, and the basic travel tools (transport and carrier rules, departure timeline, packing into bags, Travel in group checklists) are not part of Pro. Groups and Global Checklists need a registered account.
Billing. Pro is bought through Google Play or the App Store. The price, including any taxes, is shown in the app and in the store before you confirm. The subscription renews automatically at the end of each billing period (every month or every year, depending on the plan you chose) until you cancel it. From time to time we may offer a discounted price, for example for the first year; the app shows how long the discount lasts and the regular price that applies afterwards.
Cancelling. You can cancel at any time in your Google Play or App Store subscription settings. You keep Pro until the end of the period you have already paid for. Deleting your CosCheck account does not cancel the subscription.
Refunds and withdrawal. Refunds are handled under the rules of the store you paid through. If you live in the EU, you may have a 14-day right to withdraw from a purchase of digital content or services. When Pro or a tip takes effect immediately after purchase, the store may ask you to agree that this right ends once the service begins, where the law allows this. This does not affect any other rights you have under consumer law.
Tips. You can leave an optional one-time tip to support development. A tip does not unlock any features. On Android and iOS, tips are in-app purchases through Google Play or the App Store. On Windows, the "Support on Ko-fi" button opens Ko-fi, an external website with its own terms; the payment happens there, not in CosCheck.
Gifted Pro. We may grant Pro free of charge, for example to people who helped test CosCheck before launch.
We may suspend or end access for breaking these Terms or the Community Rules. You can stop using CosCheck and delete your account at any time in Account → Settings → Delete account.
CosCheck is provided "as is", without warranties of any kind. As an app made by one developer, we cannot guarantee that it will always be available or free of errors. To the extent the law allows, our liability for any claim related to the app is limited to the amount you paid us in the 12 months before the claim. Nothing in these Terms limits liability that cannot be limited under the law, or your rights as a consumer.
We may update these Terms as the app changes. The date at the top shows the latest version. Important changes will be announced in the app. If you keep using CosCheck after a change, the updated Terms apply.
These Terms are governed by the laws of Latvia. If you are a consumer living in another country, you also keep the protection of the mandatory consumer laws of the country where you live, and you may bring a claim in the courts there.
