# Stable Diffusion ## Kurzbeschreibung **"Stable Diffusion is a deep learning model used for converting text to images" / "Use Stable Diffusion online for free"** **stablediffusionweb.com **is a web interface for using Stable Diffusion models, especially Stable Diffusion XL. It offers text-to-image, a prompt database, upscaling, partly video/advanced models, and a credit-based pricing model. ## Claim Stable Diffusion is a deep learning model used for converting text to images ## Geeignet für - Images - Design / Graphics - Social Media - Video ## Kernfunktionen - Image Editing - Image Generation - Illustrations - Open Source Model ## Preismodell - **free:** Free use with a daily credit quota, a limited number of images per generation, without ads/watermarks according to the pricing page; commercial license and private images/videos are not included. - **subscription:** **Pro** Monthly credit allowance, more images per generation, no ads, no watermark, upscaling, advanced image and video models, commercial license, and private images/videos. **Max** Higher monthly credit allowance, Pro features, advanced models, commercial license, and private images/videos. - **other:** **Credit/Usage Logic** Usage is based on credits; specific consumption values depend on the function. **Contradictory Contract Presentation** Pricing describes monthly/annual plans, while the Terms simultaneously refer to a software license without recurring fees; the pricing/contract logic should be reviewed before purchase. ## DSGVO und Datenschutz **Gesamteinschätzung:** unklar / nicht verfügbar **On-prem / local hosting: indirect / not available** The website only describes a web-based service. An on-premise, local, or self-hostable deployment of the tool by the provider is not stated on the website. **Private cloud / data center: unclear** The website contains no information about dedicated environments, private cloud operation, or segregated EU/EEA data centers. **EU SaaS / managed: partial** A ready-made SaaS service is clearly identifiable, as Stable Diffusion Online is offered as a web-based service with free and paid plans. However, EU data residency or EU/EEA hosting is not stated on the website. **Hybrid: unclear** A hybrid operating model with partial local or private cloud processing and partial external processing is not described on the website. **DPA / DPA: indirect / not available** Although the privacy policy mentions that the provider may act as a processor, a specific DPA, a download, or a conclusion process is not stated on the website. **No training: unclear** The website does not state that prompts, uploads, or outputs are not used for training general models. An opt-out option for AI training is also not stated. Instead, it is only described that prompts, uploads, and outputs may be reviewed automatically and manually for policy enforcement. **Open source / transparency path: partial** There is some degree of transparency because the website names Stable Diffusion as the underlying model and discloses additional model families used in the Acceptable Use Policy. However, the website does not state any proprietary open-source provision of the platform, self-hostable components, or technical detail documentation. **Data processing** The website describes Stable Diffusion Online as a web-based service. The privacy policy mentions Google login. The Acceptable Use Policy also states that prompts, uploads, and outputs may be reviewed using automated systems and manual review. Further information on data flows, subprocessors, data residency, third-country transfers, or data centers is not stated on the website. **Conclusion** For users in the EU/EEA area, the documentation on the website is currently too incomplete to demonstrate reliable GDPR compliance. Basic privacy and usage documents do exist, but the points that are particularly important for a European assessment—EU data residency, data center location, DPA, subprocessors, certifications, and training usage—remain unaddressed on the website. Therefore, at most a very limited preliminary review is possible, not a reliable approval. **Sources** - [https://stablediffusionweb.com/private-policy](https://stablediffusionweb.com/private-policy) - [https://stablediffusionweb.com/terms-and-conditions](https://stablediffusionweb.com/terms-and-conditions) - [https://stablediffusionweb.com/acceptable-use-policy](https://stablediffusionweb.com/acceptable-use-policy) - [https://stablediffusionweb.com/en/pricing](https://stablediffusionweb.com/en/pricing) - [https://stablediffusionweb.com/prompts](https://stablediffusionweb.com/prompts) The website does mention a privacy policy and states that the service acts as a controller and processor within the meaning of the EU GDPR. However, for a reliable assessment of usability throughout the EU/EEA, key information is missing on the website, in particular regarding server location/data center, EU data residency, data processing agreement, subprocessors, international data transfers, and a contractual exclusion of training on user data. **Positive** It is positive that a dedicated privacy policy is available and explicitly mentions the GDPR. In addition, the website states that information is only collected when it is needed to provide the service, that data is only stored for as long as necessary for the requested service, and that personal data is not intended to be made public or shared with third parties, except where this is required by law. **Negative** It is negative that no server location and no EU data residency are specified on the website. A DPA is not specified on the website. A list of subprocessors is not specified on the website. Certifications such as ISO 27001 or SOC 2 are not specified on the website. An opt-out option for AI training is not specified on the website. In addition, the Acceptable Use Policy describes that prompts, uploads, and outputs may be reviewed automatically and manually, without the website explaining a more detailed data protection framework for EU/EEA users. **Server location** Not specified on the website. Neither specific server locations nor EU/EEA data centers or EU data residency are mentioned. ## Hosting und Daten - **On-Prem / lokales Hosting:** unknown - **Private Cloud / Rechenzentrum:** unknown - **EU SaaS / Managed:** teilweise / indirekt - **Hybrid:** unknown - **AVV / DPA:** unknown - **Kein Training auf Kundendaten:** unknown - **Open-Source / Transparenz-Pfad:** teilweise / indirekt ## Standort **Land:** Germany **Taxonomie:** Germany The project was initiated by researchers at Ludwig Maximilian University of Munich (LMU) (formerly Heidelberg). ## Vorteile - Easy browser access to Stable Diffusion - Free plan with daily credits - No watermark according to pricing - Commercial license according to pricing - Prompt database and easy operation ## Nachteile - Operator transparency is weak - Privacy Policy is very general - No public AVV/DPA apparent - No clear server location - Legal statements regarding CC0/output should be reviewed with caution - Not verified as an official Stability AI platform ## Quellen - Offizielle Website: https://stablediffusionweb.com/ ## Letzter Datenstand 2026-05-09 ## Originalseite https://kifox.ai/en/ki-tools/stable-diffusion-en/
