Frequently asked questions

Worker data counts as “special categories” under GDPR Art. 9 (sexual orientation, health dates from country profiles, biometrics via photos). We take that seriously:

• The worker maintains her profile herself in the Talents PWA
• Per tenant link an explicit consent with consent version
• Hard-delete workflow: on a deletion request, row, images and audit traces are fully anonymized
• Strict tenant isolation — no establishment sees another's data
• EU hosting (Germany), no third-country transfers

PostgreSQL database on a VPS in Germany (currently alpin-prod VPS). Images on MinIO/Contabo, also in the EU. Backups encrypted with 30-day rotation (so GDPR hard-delete takes effect within a reasonable timeframe).

No. On cancellation: 30 days in read-only mode so you can export your data, then hard-delete. The data processing agreement with you regulates this in writing.

The worker can request her own data export inside the Talents PWA (Plan 0018 Phase 7). You as a tenant can use the GDPR-export function in the Manager UI — produces a JSON file with all data for a specific setcard.

Two tiers: BASIS is free — claim your directory profile, pick a theme, your own website live on sosta.app. PRO costs from €9.99/month (flat package by slot count) and unlocks the worker module (worker profiles, shift booking, automatic setcard sync) plus a custom domain.

PRO starts with 30 days free. Billing by invoice and bank transfer — no credit card required. If the trial ends without payment you fall back to BASIS: your website stays online.

No. BASIS is free for good, PRO has no minimum term — if you cancel you fall back to BASIS and your website stays online.

SEPA direct debit (recommended, simplest workflow) and bank transfer. We deliberately do not support credit cards — adult-industry tenants often have problems with card acceptance, and we do not want to depend on Stripe/Paddle/Mollie (adult-AUP risk).

For DE tenants: not strictly required, we bill 19 % VAT with a standard invoice. For EU tenants outside DE (e.g. Austria, Netherlands): yes, the invoice then runs via § 13b UStG reverse charge net — you pay the VAT yourself in your country. CH/UK tenants: net, country-specific.

No. Sosta is flat-fee software, not a broker. You pay a fixed monthly fee and keep 100 % of your booking revenue — Sosta never earns on the individual transaction.

No. We are a platform, not a broker. You choose which workers you invite. The worker decides for herself which shifts she wants to book with you. Sosta structures the communication and hosts the tool, but we do no matching.

No. There is no direct customer-to-worker messaging on Sosta. The public directory (phase 2, later) shows setcards with the establishment's phone contact — contact runs via you as the establishment, not directly with the worker.

No. We built Sosta for house owners, not for developers. The editor works like a WYSIWYG tool (what you see is what you get). The only place that gets a bit technical is the DNS switch at your domain host — for that we have provider-specific step-by-step guides. And when in doubt, you write or call us.

You can either keep your WordPress and use Sosta only as an API backend (WP plugin), or migrate fully to a Sosta-hosted site (recommended). The migration guide walks you through both routes.

The Manager UI works on tablets and smartphones (responsive design) but is optimized for desktop. The Talents PWA for workers is mobile-first — installable as an app icon on the home screen, works offline for many features.

We offer an MCP server with which you can connect ChatGPT (custom GPT with connectors), Claude Desktop or Gemini directly to your Sosta account. You can then change blocks, confirm shifts or generate new about-texts in natural language.

Sosta is proprietary, but we publish our architecture patterns and compliance research transparently (e.g. ProstSchG workflow design, GDPR hard-delete strategy). If you as a developer are interested in the technical details: write to us.

Email: hallo@sosta.app — reply within one business day. For urgent problems with live tenants: an emergency phone number is in the contract.

Currently no 24/7 hotline. For onboarding help we offer 90-minute video calls (€149 once). For acute live problems (site down, etc.) you reach us via the emergency number listed in the contract.
