Frequently asked questions

Permutis is an international swapping platform for goods and services. You swipe offers, find matches and swap directly — without money between users. Available as an app (Android, iOS) and on the web.

Goods (e.g. electronics, furniture, clothing) and services (e.g. tutoring, repairs, gardening). Both are treated equally — even service-for-good.

No. Swapping itself is always free. Permutis is funded by optional plans, success boosts and credits for platform functions — never by payments between swap partners.

Register, upload up to 4 photos and add a title, description and category. Goods need a condition; services do not. AI suggestions are available within your plan limits.

Free: 3 · Plus: 10 · Pro and Champion: unlimited. The limit applies to simultaneously open outgoing 1:1 offers; own items are unlimited.

No. Prices, monetary amounts and buy/sell language are automatically blocked. Permutis is a pure swapping platform.

Left = no interest, right = interest. The feed shows offers near you, prioritised by featured offers and match score.

After a match you chat, agree on the details and swap. Structured trade offers support the flow — optionally with a voluntary credit bonus.

Formal offers in chat: which goods or services are being swapped, optionally a voluntary credit top-up from the interested party.

Only after a completed swap. The system enforces this server-side.

No. Permutis does not guarantee a swap, a match or a trade value. Credits and Founder status improve visibility, not success.

Stripe is an established payment provider for secure web checkouts. Stripe does not decide your Permutis status — the Permutis backend does.

Mobile subscriptions and purchases go through the Apple App Store and Google Play — this is a store requirement. RevenueCat wraps both worlds as an SDK and analytics layer.

The Permutis backend (Supabase) is the single source of truth. Stripe, RevenueCat and the app stores only report payment events; your actual status is decided by the backend.

Your plan, Founder and Credit status is managed exclusively by the Permutis backend. The client only displays the current status. Client-side tampering has no effect on your actual status.

Android, iOS and the web (browser) — one app for every platform.

In all 24 official languages of the European Union, as well as Arabic.
