Privacy Policy

Last updated: November 10, 2026

What Karosel is

Karosel is a service that finds winning TikTok slideshow formats, builds slideshows for your mobile app, and posts them to TikTok and Instagram accounts you connect. This policy explains what information Karosel collects, why, and what choices you have.

Information you give us

When you create an account, we collect your email address and, if you sign up with email, your password in encrypted form. If you sign up with Google, Google gives us your email address and name. During onboarding and in Settings we collect your app's name, store link, description, category, target audience, the problem your app solves, and the result it gives. We collect the screenshots and images you upload. When you connect a TikTok or Instagram account, we receive your account handle and the access permission needed to post on that account. We never ask for, and you should never give us, your TikTok or Instagram password.

Information created by using Karosel

We store the slideshows Karosel builds for you, including slide text, captions, hashtags, and sounds; the formulas it extracts; your posting queue and posting history; and the results of your posts, including views, saves, comments, shares, and install figures where they are available. We also keep basic usage records, such as when you signed in, which plan you are on, and how many concepts you have used.

Payment information

Payments are processed by Stripe. Stripe collects and stores your card details. Karosel never sees or stores your full card number. We keep a record of your plan, your payment status, and your invoices.

How we use this information

We use it only to run Karosel for you: to find winning slideshows in your niche, to break them down, to build your slideshows from your screenshots, to post them to the accounts you connected, to measure their results and improve which formulas we use for you, to bill you, to send the notifications you chose, and to support your account. We use the content of public TikTok posts, including posts that are not yours, to extract formats and formulas. A formula is a structure — slide count, order, hook type, and emotion — not a copy of anyone's words or pictures.

Who we share it with

We share information only with the services Karosel needs to work: Stripe for payments; TikTok and Instagram, through our posting provider, when we post a slideshow you created or approved; our discovery provider, which we use to search public TikTok posts; and the AI provider we use to read slideshow images and write slide text, captions, and hashtags. Your uploaded screenshots are sent to that AI provider only as part of building or analysing your slideshows. We do not sell your personal information. We do not share your screenshots, your app details, or your results with other Karosel customers. We may disclose information if the law requires it.

Cookies

Karosel uses cookies and similar storage that are necessary to keep you signed in and to remember your place in onboarding and in the dashboard. We do not use advertising cookies, and we do not build advertising profiles.

How long we keep it

We keep your account information, screenshots, slideshows, and results while your account is open. If you delete your account in Settings, Account, we delete your app details, screenshots, slideshows, formulas, and results, disconnect your social accounts, and cancel your plan. Copies in payment and invoice records held by Stripe are governed by Stripe's own policy. Backups are cleared in the ordinary course of operation.

Your choices

You can see and change most of your information in Settings. You can disconnect a TikTok or Instagram account at any time in Accounts, which stops all posting to it. You can download your Karosel data in Settings, Account. You can delete your account in Settings, Account. You can turn off optional notification emails in Settings, Notifications.

Security

Access to your account is controlled by your password or your Google sign-in. Access permissions for your connected accounts are stored securely and used only to post the slideshows you create or approve. No system is perfectly secure, and we cannot promise that information will never be accessed unlawfully, but we limit access to what the service needs.

Children

Karosel is for people building and marketing apps. It is not directed at children, and you must be old enough to enter a contract in your place of residence to use it.

Changes to this policy

If we change this policy in a way that matters, we will show the new version on this page and update the date at the top. If the change affects what we do with your screenshots or your connected accounts, we will also notify you inside the dashboard before the change takes effect.

Contact

Questions about this policy or your information: use Contact Support in Settings, Account in your dashboard, so we can identify your account.

Terms of Service

Last updated: November 10, 2026

Agreement

By creating a Karosel account or using Karosel, you agree to these Terms of Service and to the Privacy Policy. If you do not agree, do not use Karosel.

What Karosel does

Karosel finds publicly posted TikTok slideshow formats, analyses why they performed well, extracts reusable structures called formulas, builds new slideshows for your mobile app using screenshots and information you provide, and posts those slideshows to TikTok and Instagram accounts you connect — by your tap on manual plans, and automatically on autopilot plans when you have turned autopilot on. Karosel is a marketing tool. It does not guarantee views, saves, installs, sign-ups, sales, or that any post will go viral.

Your account

You must give accurate information when you sign up and keep it accurate in Settings. You are responsible for activity under your account and for keeping your password and sign-in methods secure. You may sign up only for yourself or for a business you are authorised to act for. One account may not be shared as a way to avoid plan limits.

Plans, trial, and payment

Karosel offers three paid monthly plans: Starter at $29 per month, Growth at $79 per month, and Scale at $199 per month, all in USD. Only the Starter plan includes a 7-day free trial; Growth and Scale have no trial and are charged on the day you subscribe. The Starter trial includes 5 concepts and manual posting on one TikTok account and one Instagram account. A payment card is required to start the Starter trial. You are not charged when the Starter trial starts. Unless you cancel before the Starter trial ends, the Starter plan starts automatically and your card is charged, and then monthly until you cancel. Each plan has limits — concepts per month, and number of connected accounts — shown on the Pricing section and in Settings, Billing. Concepts do not roll over into the next period. Regenerating a slideshow uses a concept. Upgrades start right away and are charged accordingly through Stripe. Switching to a cheaper plan takes effect at the start of the next payment period. Cancelling stops the next payment; your plan stays active until the end of the period you paid for, and then posting stops and connected accounts are disconnected. Except where the law requires a refund, payments are not refundable, including for a partly used period or for unused concepts.

Your content

You keep ownership of your app, your screenshots, your images, and your app information. You give Karosel permission to store, copy, resize, combine, and use them to build, schedule, and post your slideshows, to show them back to you in your dashboard and results, and to analyse their performance for your account. You promise that you have the right to use everything you upload, that it does not infringe anyone else's rights, and that the claims you ask Karosel to make about your app are true and lawful for your app and your category.

Connected accounts and posting

By connecting a TikTok or Instagram account, you authorise Karosel to post the slideshows you create or approve to that account, on manual plans when you tap Post Now or schedule them, and on autopilot plans according to your Posting settings. You are responsible for those posts as if you had posted them yourself, and for following TikTok's and Instagram's own terms and rules. You can disconnect an account at any time in Accounts, which stops further posting to it. Karosel will never post anything to a connected account other than slideshows created in Karosel.

Formulas and other people's posts

Karosel analyses public posts to extract formats and formulas. A formula is a structure, not the creator's text, images, music, or identity. Karosel rebuilds formulas with new wording and your own screenshots. You must not use Karosel to copy another person's slideshow wholesale, to impersonate another person or app, or to remove credit or watermarks in a way that breaks a platform's rules.

Acceptable use

You must not use Karosel to promote anything unlawful, deceptive, or harmful; to make false or unsubstantiated claims about an app or a product; to spam, including by connecting accounts to post misleading variations at volume; to harass or target any person; to infringe intellectual property or privacy rights; to attempt to access another user's account, data, screenshots, or results; to reverse engineer, overload, or interfere with the service; or to break the terms of TikTok, Instagram, or Stripe. We may remove content, pause posting, or suspend an account that breaks these terms.

Karosel's content

The Karosel name, the service, its software, its formula library structure, and the text and layout of its website and dashboard belong to Karosel or its licensors. These terms do not give you any right to them other than using the service as described here.

Availability

Karosel depends on third parties, including TikTok, Instagram, a posting provider, a discovery provider, an AI provider, and Stripe. Features may be delayed, limited, or unavailable when those services change or fail, when a platform restricts an account, or when a posting permission expires. A posted slideshow may be removed or limited by TikTok or Instagram under their own rules, and Karosel is not responsible for a platform's decisions about your account or your posts.

Ending the service

You may cancel your plan or delete your account at any time in Settings. We may suspend or end your access if you break these terms, if a payment fails and is not corrected, or if the law requires it. If we end the whole service, we will give notice inside the dashboard where practical. Sections of these terms that by their nature should continue — including payment for periods already used, ownership, and liability — continue after access ends.

Liability

To the fullest extent allowed by applicable law, Karosel is provided as it is, without warranties of any kind, and Karosel is not liable for lost profits, lost installs, lost revenue, loss of a social media account or following, or other indirect losses arising from use of the service. Nothing in these terms removes a liability that cannot be removed under applicable law.

Changes to these terms

If we change these terms in a way that matters, including a price change, we will post the new version on this page and update the date at the top. A price change applies from the start of a later payment period, not part-way through a period you already paid for. Continuing to use Karosel after a change takes effect means you accept the new terms.
