Terms of Service

1. Introduction

Effective date: 29 September 2026. These Terms govern your use of Katchik, a free mobile rewards programme built on TikTok, and its website.

Your contracting party is the individual resident in France who runs Katchik, reachable at support@katchik.com. There is no company. In these Terms, "Katchik", "we" and "us" mean this person.

Katchik is free: nothing is sold in the app, and no purchase is ever needed to enter or to win. Katchik is the sole promoter of every round and is responsible for every prize, including one supplied by a prize provider. The Apple and Google developer accounts are individual accounts held by the founder.

Katchik is not sponsored, endorsed or administered by, or associated with, TikTok, Meta (including Instagram), Apple or Google. Using Katchik does not give you any rights against those platforms in relation to a Katchik round.

The Official rules apply to every round, and each round has its own rules page that states its countries, timing, featured creator, points formula, ticket allocation, selection process and prizes. Read them before entering. They govern each round; these Terms govern your use of the service. The Privacy Policy explains how we use personal data.

2. Definitions

• Round: one cycle of the rewards programme.
• Featured creator: the account followed through the app-entry route. This is the previous round's winner, or @katchikapp when the chain resets.
• Mission: a task stated in the app with its points: publishing a member's own TikTok post with a specified campaign hashtag or mention, or reaching a milestone on the member's own public TikTok statistics.
• Points: the score earned from linking TikTok, capped public TikTok statistics, missions and invites under the published rules for a round.
• Tickets: the units used to weight selection. Each point held at close is one ticket, and every eligible entrant holds at least one ticket.
• Candidate: a selected person who has not yet completed acceptance and eligibility checks.
• Prize provider: a brand supplying an additional prize. A prize provider is never the featured creator.
• Sponsored card: a card in the app marked Sponsored, created by Katchik for a partner brand. Nothing is sold in the app.

3. Eligibility

You must be at least 18. The app is rated 18+. You must live in a country permitted by the rules for the round you enter.

The closed beta is for residents of the United Kingdom, Germany and France. Other countries and territories are not eligible unless a later round's rules open them. The United States, Italy, Poland, Spain, Brazil, Australia and Quebec are excluded.

You may have one Katchik account. You may link one TikTok account to it. Katchik staff and members of their households cannot win.

4. Registration and account security

You create and sign in to your Katchik account with your email address and password. You link TikTok afterwards through TikTok Login Kit. TikTok is never a way to sign in to Katchik.

Keep your email address accurate and protect your password. Do not let another person use your account to enter for you. Write to support@katchik.com if you believe someone has accessed your account without permission.

5. Rounds, points and free entry

Following @katchikapp on TikTok is required to earn points, do missions and join rounds. You follow it yourself, once, in TikTok's own app, and confirm it in Katchik; until then those features stay locked. We check it only if you are selected, against Katchik's own follower list. The free web entry needs no follow.

To enter a round through the app, link your TikTok account, follow the featured creator yourself in TikTok's own app, and return to Katchik to confirm: "I followed, count me in". Katchik never automates a follow. A follow alone does not enter you.

Keep following the featured creator until the round's winner is announced; after that you may unfollow.

A round closes at its published deadline or when it reaches its published number of players, whichever happens first. App entries and valid free entries count towards the same number of players.

You can instead enter on equal terms, under the same ticket rule as every entry, through the web form at katchik.com/free-entry. No follow and no app are needed to enter by this route. There is no free-entry path inside the app, and the app tells you that the web route exists.

The web form asks for the round, your full name, country, email address, TikTok username, confirmation that you are 18 or older, and acceptance of the rules. Confirm your email through the one link we send. You may submit one free entry per person per round. Using both routes does not create a second entry: if the same person enters a round twice, we keep the first valid entry.

App points come from linking TikTok, capped public TikTok statistics, missions and invites. We read your own public mission videos through TikTok's video.list permission. Points cannot be bought. Every eligible entrant has at least one ticket.

Katchik sets the scoring formula and all caps for each round. They may change between rounds, but never within a round once it opens. Each round's rules show the formula version and caps before entry opens, and the Official rules explain how a free entry's tickets are counted.

6. Selection and prizes

At close, the entry list is sealed and its cryptographic fingerprint is published. In list-based mode, the eligible list is also sealed and fingerprinted after the challenge window below. Randomness comes from the public drand quicknet beacon, with the beacon round pinned only after the last seal. Selection is deterministic once the sealed inputs and beacon value are fixed. A public proof page and verification script let anyone repeat the calculation.

Each round's rules state its verification mode. In candidate-first mode, the default, we select a candidate weighted by tickets and check that person's required follows: the featured creator, and @katchikapp against Katchik's own follower list. If a check fails, we move to the next position. A web entrant is exempt from the follow requirements and never fails because they did not follow.

In list-based mode, app entries are checked against the featured creator's own TikTok follower export. A 24-hour challenge window runs before the eligible list is sealed, and app participants raise disputes in the app. Valid web entries are included separately without a follow check. If you entered in the app and are selected, we still check your @katchikapp follow against Katchik's own follower list.

How likely you are to be selected depends on your tickets and the total number of tickets in the sealed list used for selection. It also depends on any earlier candidates being ineligible, declining or not answering. Sponsorship never changes how likely anyone is to be selected.

A selected person remains a candidate until they accept within 48 hours and pass the public-account and good-standing checks stated in the rules. We publish their handle and profile photo only after that process. The winner must keep their TikTok account public until the next round is finalised. If the next round, where the winner is the featured creator, is list-based, the winner must supply their TikTok follower export if we ask, as explained in the rules.

If a candidate declines, does not answer in time or fails the stated checks, the next eligible person in the selection order is considered. If nobody is left, @katchikapp is featured in the next round. A partner prize that no one can accept is carried to the next round and stated in its rules.

The main prize is being the featured creator of the next round. People entering that next round through the app must follow the winner; the web route remains exempt. No number of followers is promised.

A round may also offer a prize supplied by a prize provider. Its nature, quantity, approximate value, claim deadline and award date appear in the rules. There is no cash alternative. Katchik remains responsible for it.

The winner claims an additional prize in the app before the deadline in the rules. A winner who entered on the web claims by replying to our email. Delivery details go only to whoever sends the prize, Katchik or the prize provider, only to send it, and are deleted 90 days after delivery.

7. User conduct

• Give accurate information about your identity, age, country and linked account.
• Do not create extra accounts or use both entry routes to obtain duplicate entries.
• Follow @katchikapp and the featured creator yourself in TikTok's app. Do not use automated follows.
• Do not falsify statistics, mission evidence, follow evidence or prize claims.
• Submit only your own mission posts. Use the campaign hashtag or mention stated for the mission.
• When a mission is for a brand, disclose the connection in your post with a clear label such as "Ad", "Werbung" or "Publicité". Use TikTok's commercial-content disclosure setting when applicable; the text label does not replace that setting.
• Make any statement about a brand truthful and based on your actual experience. Do not claim to have used a product if you have not.
• Do not interfere with security checks, the entry list, the selection calculation or the proof page.

8. Content

Your mission posts remain your content on TikTok. We read the public video information needed to check a mission, calculate points and resolve related disputes. These Terms do not grant us a general right to reuse your posts in advertising.

9. Sponsored cards

Some cards in the app are marked Sponsored. Katchik creates them for partner brands: a brand video or a partner mission. Nothing is sold in the app. A partner mission earns the points it states, like any other mission; being sponsored never adds an entry, a point, a ticket or any other advantage in a round.

10. Changes to the service and these Terms

We may revise these Terms for future use of the service. We will identify the new version and tell you about material changes by email and with a notice in the app, at least 30 days before they apply, except changes required by law or for security, which apply when published.

Changes to the scoring formula or caps apply only to later rounds whose rules show them before entry opens. We will not retrospectively reduce an entry's rights through a general update. If an exceptional legal or technical problem affects an active round, its rules govern the response.

11. Suspension, account deletion and TikTok disconnection

We may investigate or suspend activity where there is a reasonably supported concern about age, duplicate entries, fraud, unlawful advertising or interference with the service. We will explain the reason and let you request a review at support@katchik.com, unless doing so would be unlawful or compromise an active security investigation.

You can request account deletion at katchik.com/delete-account through an emailed link. You have 30 days to cancel the request. After that, your account data, points, missions, round history and TikTok connection are erased.

Published proofs keep fingerprints only, without your handle or account link after deletion. The Privacy Policy explains how long we keep each kind of information.

While a deletion is pending you are signed out everywhere and your account keeps its points. At erasure, your entries in rounds that have not closed are withdrawn, a prize claim you already submitted is still delivered, and a claim you had not submitted lapses.

Disconnecting TikTok revokes the token at TikTok and purges the TikTok data we hold, except a keyed hash of your TikTok account ID that stops the linking credit being earned twice, kept after you disconnect TikTok, and for 12 months after your Katchik account is erased. It does not change your email-and-password sign-in. Deauthorisation in TikTok also triggers a purge when we receive the event. Missions waiting for verification stop, stats points are reversed, the linking points stay (linking the same TikTok account again never earns them twice), and entries you already made stay in their rounds; the check at selection still applies.

The optional 30-day cancellation window does not postpone your statutory data rights. Requests to erase data sooner are handled under the Privacy Policy.

12. Responsibility and your rights

Katchik is responsible for running its rounds and providing the prizes described in their rules. A prize provider's involvement does not transfer that responsibility to you or remove it from Katchik.

We cannot control whether another person keeps following a TikTok account or whether TikTok remains available. We do not promise a follower total or continued engagement. Those limits do not excuse misleading prize descriptions or remove your mandatory rights.

Nothing in these Terms excludes liability that cannot lawfully be excluded. There is no general requirement for you to compensate us for all claims arising from your use of the service.

13. Governing law and jurisdiction

French law governs these Terms. This choice does not remove the mandatory consumer protections of the country where you usually live (Rome I Regulation, Article 6).

You may use any court available to you under mandatory jurisdiction rules. These Terms do not require a consumer to bring every claim exclusively in France.

Contact us first if you want help resolving a dispute. You keep the courts and remedies your country's mandatory law gives you.

These Terms are in English. See also the Official rules, the Privacy Policy and the legal notice.
