Backend hosting by Contabo

The App backend and its database are hosted by Contabo GmbH, Aschauer Straße 32a, 81549 Munich, Germany. Contabo processes data on our behalf under a data processing agreement pursuant to Art. 28 GDPR. Hosting is necessary to provide the requested service (Art. 6(1)(b) GDPR) and to operate it securely and reliably (Art. 6(1)(f) GDPR).

Data processed by us

When you use /upscale, you can upload an image through Discord or provide an image URL. For uploads, the App retrieves the image from the attachment URL supplied by Discord. The App processes the image URL, image bytes and dimensions, your Discord user ID, a hash derived from that ID, your credit balance, and technical request information required to provide and secure the service. Discord IDs and images may be personal data.

Purpose and legal basis

The data is processed to validate the request, upscale the submitted image, return the result through Discord, prevent abuse, and manage credits. Processing required for the command is based on Art. 6(1)(b) GDPR. Security, abuse prevention, and reliable operation are based on our legitimate interests under Art. 6(1)(f) GDPR.

Storage by us

The App does not write input or output images to persistent storage. Image bytes are held temporarily in working memory while the request is processed and are released afterwards. The Discord ID, its hash, and the associated credit data are stored while the service or the credit account remains active, unless earlier deletion is requested and no legal obligation requires continued storage.

Image processing by Modal Labs

The submitted image is transmitted to Modal Labs, Inc., a Delaware corporation in the United States, and processed on our behalf using SwinIR for photos or Swin2SR for screenshots and text. Modal acts as our processor under a Data Processing Addendum incorporated into our service agreement.

Data location and international transfers

Normal requests are routed through Modal's eu-west region and processed within its EEA-wide eu region. If European capacity is unavailable, image processing may fall back to the United States. The fallback uses Modal's us-east routing region and US-only us compute region. Images are therefore not guaranteed to be processed exclusively within the EEA. Modal is a US company and uses subprocessors. To the extent personal data is transferred to the United States or another country outside the EEA, the transfer is protected by the EU Standard Contractual Clauses incorporated into Modal's Data Processing Addendum pursuant to Art. 46 GDPR.

Storage by Modal

The App uses Modal's Server primitive. According to Modal's security documentation, Server request and response payloads are not stored and are proxied directly to the container. Application access logging is disabled and the App does not log image content. Modal may retain technical app, container, security, and account metadata in accordance with its documented retention periods.

Further information

See Modal's Privacy Policy, Security and Privacy documentation, Data Processing Addendum, and Subprocessor List.

Automatic image classification by OpenAI

The submitted image is also sent to OpenAI's Decisions API to automatically select between photo and screenshot processing in the background. We do not include your Discord ID, credit balance or source URL in that request. Uncertain or unavailable classification uses screenshot mode. No OpenAI image generation or recreation is performed.

This classification supports the requested service under Art. 6(1)(b) GDPR. OpenAI processes API data under its applicable service and data processing terms. API data is not used for model training by default. Standard abuse-monitoring logs may be retained for up to 30 days, subject to exceptions and account controls; we do not promise zero retention or EU-only processing for classification. See OpenAI's privacy policy and API data controls.

Discord

The source image is supplied through Discord and the result is posted as a Discord attachment. Discord processes this data under its own terms and privacy policy. See https://discord.com/privacy.

Sensitive content

Do not intentionally submit images containing special-category personal data under Art. 9 GDPR, images of minors, authentication documents, payment information, medical records, or other highly sensitive or confidential information. If we learn that such content has been submitted, we will stop processing it and delete any data under our control where technically possible.

Your rights

Subject to the applicable legal requirements, you have rights of access, rectification, erasure, restriction, data portability, and objection. You may contact us at info@diszy.com. You also have the right to lodge a complaint with a competent data protection supervisory authority.

By adding the Discord App Upscale Bot, application ID 1185135006113333258 ("Upscale Bot"), to your or any other Discord server, you understand and agree that:

• If you use /upscale with a Discord image upload or an image URL, Upscale Bot downloads the image and processes it with the open-source Real-ESRGAN model on cloud infrastructure provided by Modal Labs, Inc. The result is returned to Discord as an attachment.
• The Modal deployment uses an authenticated Modal Server with request routing in eu-west and computation restricted to the EEA-wide eu region. Modal documents Server request and response payloads as zero-retention: they are proxied directly to the container and are not stored by Modal. Application access logging is disabled.
• Upscale Bot does not write input or output images to persistent storage. Image bytes are held temporarily in working memory during processing. The following account and credit data is stored or updated:
  • Discord ID
  • Hash of Discord ID
  • Credits Balance of Discord ID
• The source image and resulting attachment are also processed by Discord under Discord's own terms and privacy policy.
• You must have the necessary rights to submit the image. You must not intentionally submit illegal content, content that infringes third-party rights, special-category personal data under Art. 9 GDPR, images of minors, authentication documents, payment information, medical records, or other highly sensitive or confidential information.
• AI upscaling may generate inaccurate or artificial details. You are responsible for reviewing the result before relying on or publishing it.
• Processing requests incurs costs for the Bot operator (Niklas Müller, Johann-Sebastian-Bach-Str. 23, 34134 Kassel, Germany, info@diszy.com). Once free credits are depleted, credits are required to continue using the main functionality.

Slash Commands

/upscale upload:[image]	Attach a JPEG, PNG, or WebP image directly in Discord to double its width and height.
/upscale image:[url]	Alternatively, paste a public image URL. Choose either upload or image, not both.
/credits balance	Shows your current credit balance.
/credits gift	Gift credits to another user.
/credits topup	Get a link to top up your credits.
/credits info	Details about total credits spent, received, and initial funding.

Images must be at most 10 MiB and 12 million pixels, with neither side exceeding 8,191 pixels. Animated images are not supported. Do not submit sensitive personal data.

Upload an image or paste its URL; no image-type selection is needed. The bot automatically classifies it using OpenAI and chooses photo or screenshot upscaling in the background. Photos use SwinIR; screenshots use Swin2SR and lossless output. Detection is probabilistic; uncertain or unavailable classification uses screenshot mode.

You can run one upscale at a time. Submitting another request while it is processing will not start another job or reserve additional credits.

Your result is private and includes the original and final dimensions. Use Download image to open the full-size result and save it, or Share to channel to post it in the server channel.
