Terms of Service

Provider and contact

Provider identification, a serviceable address and general contact channels are set out in the legal notice (Impressum). These terms govern the relationship between Permutis as a technical platform and the persons who use the website, web app, mobile apps or connected services.

Permutis provides features for discovering, initiating, coordinating and documenting swaps. Permutis does not thereby become the owner, a broker in the legal sense or a contracting party to the specific swap between users. Users remain responsible for whether they enter into a swap, which information they exchange and whether their offer is lawful.

Covered platform areas

Covered areas include in particular the website, web app, mobile apps, user account, profile, offer management, swipe discovery, matches, chats, reviews, reports, support, trade-up challenges, Founders and partner features, and optional platform services such as visibility, boosts, AI support and subscriptions.

Additional terms of individual app stores, payment providers, hosting providers or technical service providers may also apply where users use those services directly. In addition, the privacy policy, cookie policy, community and offer guidelines, challenge rules, Founders Club notices, partner programme rules and specific feature notices form part of the Permutis rules where they are relevant to the respective use.

In the event of conflicts within Permutis documents, more specific policies for individual features take precedence over general descriptions, provided they do not unfairly disadvantage users. Mandatory statutory rights, consumer rights and data protection rights remain unaffected.

Status

Last updated: 9 September 2026. These terms describe Permutis as a money-free swapping platform: no prices or demands for money between users.

Supplementary notices may apply for individual features, in particular for app-store subscriptions, payment providers, withdrawal, cancellation, trade-up challenges, privacy, cookies, the partner programme and support processes.

Age and legal capacity

Permutis may be used from the age of 14. This includes ordinary swaps such as football cards or postage stamps. Users aged 14 to 17 may enter into legal transactions, including platform subscriptions, independently only to the extent that they can validly do so under applicable law; otherwise, consent from their legal representative is required. Legal entities or organisations may only use Permutis if the acting person is authorised to represent them and all information provided is accurate.

Use by children under 14 is not permitted; their accounts may be suspended. Content, profiles, messages and offers that endanger, sexualise or exploit minors, or facilitate targeted harmful contact, are prohibited. Ordinary, legally permitted swaps by users aged 14–17 remain allowed.

Only users whose identity has been verified and whose age of at least 18 has been confirmed through proof of identity and age may view or post content and listings in the 18+ area (FSK18). A self-declared age alone is not sufficient.

Account management and electronic communication

An account may only be maintained with accurate, up-to-date and personal information. Users must keep their contact address reachable, because legal notices, security alerts, support replies, contractual information and changes may be communicated electronically by email, app, website or in-app messages.

Users may not operate accounts for suspended persons, create circumvention accounts or use automated access. Permutis may request evidence where verification, suspected abuse, the partner programme, payouts or security checks make this necessary.

Suspension, restriction and termination

Users may close their account using the available features or via support. Open support cases, abuse investigations, statutory retention duties, payment records for platform services or security reasons may require certain data to be retained temporarily.

Permutis may restrict features, deactivate offers, reduce visibility, suspend or terminate accounts if users breach the law, these Terms, policies, security rules, challenge rules, privacy requirements or the no-money rule. In serious risk cases a measure may take effect immediately; in less serious cases Permutis may first warn or require remediation.

Swap logic

Permutis is designed for swaps. An offer may be a good, a service or a skill. A permitted swap exists where users voluntarily agree to exchange one offer for another offer without one user demanding a price or a monetary payment from the other.

The platform supports initiation through profiles, offers, categories, swipe decisions, matches and chats. A match only means mutual interest. Whether a swap takes place, which handover method is chosen and whether an offer meets expectations is for the participating users to clarify under their own responsibility.

No prices, no purchase prompts

Users may not set prices for offers, formulate purchase prompts, state sales conditions or demand money. Circumventions are also prohibited, such as “payment only”, external payment links, price lists in images, price statements in chat, “or best offer” wording, or references to external classifieds and shop listings.

Permutis may technically filter money terms, price terms or buy/sell terms, reject content, deactivate offers, review chats and restrict accounts where such terms are used as an offer condition or sales intent. Mentioning such terms remains permitted in rules, warnings, support cases or legal texts where it is clear that they describe a prohibition or a distinction.

Credits are not an offer condition

Credits are internal platform points and must not be used as a required counter-performance for a user offer. A provider may therefore not state that a good or service will only be swapped for credits. Credits do not replace a real swap and must not be used as a price, substitute currency or mandatory payment between users.

Outside challenge swaps, credits may only be mentioned or offered voluntarily and without a mandatory condition in addition to a real swap item. They must never be demanded, used as a substitute for a swap offer, or imposed as a condition for completing a swap. For challenge swaps stricter rules apply: no credits, no money, no extra items and no services, where the respective challenge rule so provides.

Account and security

Users must provide accurate, current and complete information where this is required for account, security, swap, verification or support. Access credentials must be kept confidential. Suspicious access, password loss or account misuse should be reported without delay.

Accounts must not be sold, rented, transferred, created in automated bulk or operated for third parties. Also prohibited are identity deception, false verification, profile imitation, circumvention of a suspension, manipulation of reviews, automated scraping, spam, bot use and any use that impairs the security or availability of the platform.

Offers, images and rights

Users are responsible for the title, description, images, category, condition, availability, collection or handover notes and lawfulness of their offers. An offer must truthfully describe what is actually to be swapped. Defects, limitations, missing accessories, faults, wear or special prerequisites of a service must be stated transparently.

Titles and descriptions must not contain stealth advertising, affiliate or advertising links, shop links, social-media promotion, spam, keyword stuffing, hidden contact channels, third-party brand advertising without factual relevance, or other activity that does not serve an honest description of the swap item. Links are only permitted where Permutis expressly allows them for a feature or where they are required for security, proof or support.

Images must show the actual offer or be clearly recognisable as a supplementary illustration. Users may only upload content for which they hold the necessary rights. Third-party product images without permission, stock photos presented as one’s own item, hidden contact information, personal data, watermarks of other platforms or content that infringes third-party rights are not permitted.

Prohibited offers

All offers are prohibited where possession, transfer, advertising, performance or swap is unlawful, unsafe or subject to special permits that the user cannot evidence. This includes in particular illegal goods or services, weapons, ammunition, hazardous substances, drugs, prescription or regulated medical products, counterfeits, stolen goods, personal data, official documents, financial products, cryptocurrencies as swap content, sexual services, hate content, extremist symbols, animal trade, products relevant to species protection and products with safety risks.

Permutis may block or restrict additional categories where abuse, legal risks, youth protection, product safety, platform integrity or community protection so require. In case of doubt Permutis may request evidence, hide an offer until clarification or remove it permanently.

Matches, chats and performance

A match indicates mutual interest and does not automatically oblige either side to complete a swap. Before handover, users should clarify all material points: condition, scope, accessories, place, time, safety questions, specifics of a service and whether both sides understand expectations the same way.

For displaying, sorting and recommending possible swap partners, Permutis may use matching signals such as own offers, sought categories, wish lists, swipe decisions, radius, approximate location, language, region, reviews, security status, voluntary profile details such as age group or gender, and cookie and preference data, to the extent their use is permitted under privacy and cookie rules.

These matching signals serve to produce more relevant suggestions and to increase the chance of suitable swaps. They do not create a right to a particular match, a guarantee of a successful swap, an obligation to accept a suggestion, or a right to disadvantage users on prohibited criteria.

Permutis provides the technical platform and is not a party to the specific swap between users. Handover is at the users’ own risk. Users should prefer public, safe places, not share sensitive data unnecessarily and use the platform chat so that arrangements remain documented.

Trade-up challenges

Trade-up challenges are a special game mode with additional rules. In Challenge V1 the following applies: exactly one challenge item against exactly one other item, no credits, no money, no extra items and no services. Only completed swaps confirmed by both sides count for progress, ranking or public challenge stories.

Permutis may review challenge participation, remove invalid steps, correct rankings, exclude users from challenges or withhold stories where manipulation, sham swaps, pressure, impermissible counter-performance, multiple accounts or rule circumvention are apparent.

Reviews

Reviews should help the community identify reliable swap partners. They must be truthful, factual, comprehensible and related to the specific completed swap. Aspects that may be rated include communication, punctuality, condition, handover and overall impression.

Fake reviews, purchased or coerced reviews, threats, pressure, retaliatory reviews, discriminatory statements, publication of personal data and reviews of events that did not take place are prohibited. Permutis may hide, correct or remove reviews that breach rules or rights.

Subscriptions, add-ons, credits and Founders Club

Paid or credit-based platform services cover only Permutis features such as visibility, boosts, AI assistance, enhanced features, credit packs, subscriptions or the Founders Club. They are not a purchase price for users’ offers and do not guarantee a successful swap.

For some add-ons, additional digital services may be unlocked with credits, for example visibility, special placements, AI support or other clearly designated platform features. Such add-ons concern exclusively Permutis services and must not be understood as payment to other users.

The Founders Club provides platform benefits. It is not an investment or an acquisition of company shares or securities, and it creates no profit-sharing entitlement or guaranteed increase in value. The relevant offer information sets out the membership’s scope and conditions.

For subscriptions, digital content, credit packs, boosts or other chargeable platform services, term, renewal, cancellation, withdrawal, immediate performance, app-store processing, payment providers and refund rules are described in the respective offer information. Consumer rights remain unaffected.

Before taking a paid subscription, users should use the free offering to test core features, offer creation, swap logic and usability. The paid subscription is intended for extended platform features and does not replace users’ own assessment of whether Permutis fits their usage.

Vouchers provide only the platform benefits displayed before redemption: a fixed-term subscription entitlement, immediately credited credits or an ongoing Founder membership under its terms. They are not cash-redeemable balances or swap prices. The redemption window, benefit duration, eligibility criteria and total and per-user limits are separate conditions of each voucher.

Only one voucher entitlement may run at a time per account. No other voucher may be redeemed while it is running. Credit vouchers are fulfilled when the credits are added and do not form an ongoing subscription entitlement. A code limited to one use per user account cannot be redeemed again, even after its benefit expires.

Paid upgrades to a higher plan or the Founder Club remain available at any time. An upgrade does not end a running voucher; it continues to block other codes until its scheduled end. Vouchers neither cancel nor change existing Stripe or app-store subscriptions and do not trigger automatic paid renewal. Manage existing subscriptions separately with their provider.

14-day withdrawal for subscriptions and digital platform services

Consumers generally have 14 days from entering into an online contract for paid platform services to withdraw, unless a statutory exception applies. This right concerns the platform contract; individual swaps between users are separate.

Merely using an ongoing subscription, for example to post an offer, does not extinguish the right of withdrawal. A proportionate payment for services supplied before withdrawal is due only where the statutory conditions are met, including proper information and an express request for early performance.

For paid services, the right of withdrawal ends early only after full performance, where performance began with prior express consent and the consumer had acknowledged that full performance would end that right. Partial use of an ongoing subscription is not sufficient.

Different conditions apply to digital content supplied without a physical medium: for paid content, the right ends when performance starts only if the consumer expressly consented to this before the withdrawal period expired, acknowledged the resulting loss of the right and received the legally required contract confirmation on a durable medium.

The type of service and applicable withdrawal rules must be explained before ordering. Withdrawal information and a model form must be accessible, and required consents must be obtained separately. These terms do not restrict mandatory consumer rights.

Subscription term, renewal and cancellation

Monthly or annual subscriptions agreed as recurring generally renew at the billing interval displayed when the contract is made. One-off platform services and fixed-term voucher benefits do not thereby become paid subscriptions. The terms agreed before contracting and mandatory consumer rights govern.

End automatic renewal in good time before the next renewal through the relevant payment provider’s or app store’s subscription management. The term, next billing date and agreed cancellation conditions shown there apply. These terms introduce no additional cancellation deadline.

Cancellation stops future renewals; paid entitlements generally remain available until their period ends. Statutory withdrawal, refund and other consumer rights remain intact. Deleting a Permutis account does not automatically cancel an externally managed subscription.

Manage web subscriptions through the provided Stripe subscription portal and app-store subscriptions through the relevant store. Permutis claims a renewal only if it was validly agreed and all mandatory information and notice requirements were met. If those conditions are missing, the renewal creates no additional payment obligation.

Earn credits

Coins or credits are internal platform points for Permutis features, for example visibility, boosts, special placements, AI support or other clearly designated platform services. They are not legal tender, not an e-money function, not a balance for user offers, not an investment, not a right to payout, and cannot be exchanged back into money or otherwise claimed as money.

Credits are primarily earned through enabled activities. Buying is optional; package quantity and platform price are shown before confirmation.

Under the new model, only earned credits can be transferred as a voluntary extra to a genuine two-sided swap. They may not be demanded. Cash withdrawal is excluded; mandatory refund rights remain unaffected.

Purchased coins/credits are credited to the account after successful payment confirmation. Upon use for boosts, visibility, AI features or other digital platform services they are considered consumed. Consumed coins/credits are generally not reversed once the service has been technically provided, unless mandatory consumer rights, error corrections or goodwill decisions require otherwise.

Crediting or using credits does not automatically remove the statutory right of withdrawal. The decisive factors are whether the particular benefit is a service or digital content and whether its stated statutory conditions have actually been met. Mandatory refund rights remain unaffected.

There is no balance cap. Once the new model is activated, at most 100 new activity credits apply per UTC calendar month. Purchases, received swap extras and refunds are excluded.

After announced activation, earned credits may expire after 90 days without a genuine live listing. The period starts when the last listing goes offline. No expiry period runs while at least one genuine listing is live. Purchased credits do not expire.

After activation, qualifying activity rewards are pending for 7 days. Conditions, event limits and remaining monthly rewards are displayed. The monthly limit concerns new activity rewards, not purchases or refunds.

Earn credits: Credits page.

Moderation and reports

Permutis may review content automatically or manually, restrict or remove it, deactivate offers, hide chats, reduce visibility, warn, suspend or delete accounts where content breaches the law, these terms, community guidelines, security rules or the no-money rule. Users may report suspicious content, messages, profiles or swaps.

When reviewing, Permutis may consider context such as repetition, severity of the breach, risk to other users, deceptive intent, willingness to cooperate and legal duties. Obviously unlawful or dangerous content may be removed without prior enquiry.

Admin and support access

Support and admin access is purpose-bound, role-based and audit-logged. Access to chats, reports, profile data, offer data or usage data occurs only where required for support, security, moderation, abuse prevention, legal duties, fault analysis or platform operations.

Permutis should limit internal permissions to what is necessary, log particularly sensitive access and review it regularly. Employees, contractors or agents must not use data privately, for unrelated purposes or outside their role.

Platform role and liability limits

Permutis provides a technical platform and does not owe the conclusion, performance, quality or success of a swap between users. Permutis does not generally pre-screen offers and gives no warranty that user statements, identity, availability, condition, rights or performance capability of other users are complete or correct.

Permutis liability is governed by mandatory law. Liability for slight negligence may, where legally permitted, be limited to breaches of material contractual duties and foreseeable damage. Liability for intent, gross negligence, injury to life, body or health and mandatory statutory claims remains unaffected.

Availability, changes and security

Permutis strives for stable operation but cannot guarantee uninterrupted availability. Maintenance, security measures, technical faults, third-party outages, app-store requirements, abuse prevention or force majeure may temporarily restrict features.

Permutis may change, remove, limit or further develop features where required for security, legal, product, performance or abuse reasons. For material changes to chargeable platform services, users should be informed appropriately.

Rights in user content

Users retain their rights in images, texts, profile details, reviews and other content, but grant Permutis the rights to store, reproduce, technically adapt, display, translate, moderate and make such content available within the platform to the extent required.

Users warrant that they hold the necessary rights and do not infringe third-party rights. External advertising, press, social media or public success stories require a separate clearance unless a statutory basis or an already granted specific consent exists.

Reporting, reasons and complaints

Users may report unlawful content, prohibited offers, safety risks, suspected fraud, rights infringements or rule breaches. Permutis should review reports in a comprehensible manner, document appropriate measures and inform affected users of material decisions where required.

Where features are restricted, accounts suspended or content removed, an appropriate complaint channel should be available where legally required or practically possible. Abusive reports, false complaints or repeated unfounded reports may themselves be treated as a rule breach.

Changes

Permutis may change these terms where features, legal requirements, security needs, app-store rules, technical processes or the business model change. Material changes should be communicated transparently, for example via website, app, email or in-app notice.

Where required by law, changes take effect only after appropriate notice or consent. Already completed swaps remain unaffected by later changes unless mandatory law provides otherwise.

Contact and supplementary documents

Provider identification and contact details are in the legal notice (Impressum). In addition, the privacy policy, cookie policy, community and offer guidelines and special rules for individual features such as trade-up challenges, Founders Club, partner programme or support processes apply.

For questions about suspensions, reports, privacy, account, payment status for platform services or security cases, users should use the official support channels. Legal notices must be directed to the contact point named in the legal notice.
