Terms of Service

Version 1.0 · Effective 6 October 2026

1. Operator and Agreement

Sevli at https://sevli.app is operated by YANG YANG as an individual operator based in China. These terms govern the AI image generation and editing service. By creating an account or purchasing a plan or credits, you confirm that you are at least 18, can enter this agreement, and accept these terms and our Privacy Policy.

2. The Service and Models

Sevli is an independent digital software service for generating images from prompts, editing reference photos, product photography, portraits and creative effects. Purchased access and credits are provided after payment confirmation. Image availability and generation time depend in part on external model providers.

Requests are processed through APIMART. Available catalog entries include GPT Image 2, Nano Banana 2 / Nano Banana Pro (Gemini), Seedream 5.0, Qwen Image 3.0, and the APIMART channel entries labeled GPT Image 2.5 Flare / Sunburst. The generator identifies the model chosen for a request. Channel labels do not imply official endorsement of Sevli by any model company.

3. Accounts

Use accurate account and billing information, keep your credentials confidential, and notify support@sevli.app of suspected unauthorized use. You are responsible for activity under your account and for the rights and permissions needed to upload reference images.

4. Plans and Credit Packs

Sevli uses a hybrid billing model: recurring subscriptions with monthly credit allocations, plus separate one-time credit packs. Prices, allocations and pack validity are shown on the Pricing page or in the credit-purchase dialog before checkout. Buying an additional credit pack currently requires an active subscription. Credits are a service allowance, not cash, and cannot be transferred or redeemed for money.

5. Payment Authorization and Renewal

When subscribing, you authorize recurring charges for the selected monthly or annual plan until renewal is canceled. The subscription renews automatically at the end of its billing period unless you cancel in advance. Annual plans are charged annually and allocate their included credits monthly. Each credit-pack purchase is a separately authorized one-time charge; Sevli does not offer automatic credit top-ups.

Payment card information is handled by the payment provider selected at checkout, including Stripe or Waffo Pancake. For Waffo checkout, Waffo Pancake acts as Merchant of Record and handles payment and applicable tax collection. Sevli does not store full payment card numbers. Any applicable taxes and the final amount are displayed in checkout before payment. A future price change applies only after notice, not retroactively to an already-paid period.

6. Online Cancellation

Sign in and go to Account settings → Billing, select your subscription and use the cancellation control. You may also request assistance at support@sevli.app. Canceling renewal keeps the already-paid subscription until its period ends and prevents the next renewal; it does not automatically refund a previous payment. Separate credit packs keep their original validity after cancellation. Cancellation alone does not delete your account or images.

7. Credit Validity and Consumption

Included subscription credits do not roll over: each monthly allocation expires at its allocation-period end. The $10 / 600-credit pack is valid for 30 days; the $20 / 1,400-credit pack for 90 days; and the $50 / 4,000-credit pack for 180 days. Existing purchases retain the validity promised when they were bought.

New accounts signed in with Google receive a one-time 100-credit reward valid for 7 days. Google-linked accounts can claim 10 daily check-in credits, expiring at the next 00:00 UTC. Email/password accounts without Google sign-in do not receive welcome or daily credits. Reward availability and the credit cost of a requested model and settings are shown in the service.

Credits with the earliest expiry are consumed first, regardless of whether they came from a reward, subscription or pack; non-expiring credits are consumed last. Failed generation returns the affected generation credits under their original validity rules. This credit return is separate from a cash refund.

8. Refunds and Billing Disputes

Our Refund and Cancellation Policy explains how to request a review. Contact support@sevli.app with your order reference and account email if you believe a charge is wrong or a purchase was not delivered. Requests are reviewed using delivery, usage and applicable law; mandatory consumer rights are not excluded. Refund requests and subscription cancellation are separate actions.

9. AI Content and Rights

You retain your rights to your input. You give us the limited permission necessary to process, moderate, store and return your requested content. We do not operate model training on your inputs; processing by external providers is described in the Privacy Policy. Permitted use of outputs is subject to your rights to the inputs, applicable law and the selected model's terms. We do not promise that every output is unique or legally protectable.

Never-paid accounts receive a Sevli watermark on new outputs. Accounts with a successful payment history, including a credit-pack purchase, receive new outputs without that watermark even after their subscription ends.

10. Content Rules

Our Content and Acceptable Use Policy applies to prompts, reference images, generated results and shared content. The following six categories are prohibited:

1. Pornography / NSFW: explicit sexual content, pornography and non-consensual intimate imagery.
2. Violence / gore: graphic violence, bloody imagery, terrorist content and encouragement of serious harm.
3. Hate speech: hateful abuse, threats or dehumanization of protected groups.
4. Child safety / CSAM: sexualized minors, child sexual abuse material, grooming and other exploitation or endangerment of children, including synthetic depictions.
5. Deepfakes / impersonation: harmful or deceptive impersonation, fake endorsements and non-consensual or misleading synthetic depictions of real people.
6. Copyright / trademarks: content infringing intellectual property, privacy or publicity rights, or unauthorized use of protected material and branding.

Moderation: SeeAPI checks user prompts and reference images before generation and output images before they are displayed or saved. The selected model provider also applies its safeguards. Required checks failing or becoming unavailable stop the request; selecting another model does not bypass platform checks. Automated checks may make mistakes; lawful requests can be referred to support for review.

Reporting: Email support@sevli.app with the relevant image or shared-page link, the reason for your report and any useful rights or consent information. Signed-in users may also submit a support ticket. Use the same address to appeal a decision.

Enforcement: We investigate reports and may reject requests, restrict access, disable shared content, or suspend or terminate service for serious or repeated abuse. We may preserve records and report illegal material where required by law. Do not bypass safeguards, systematically scrape outputs or evade payment controls. AI content is not verified professional advice or evidence of a real event.

11. Privacy

Our Privacy Policy covers data processing, provider disclosure, retention and requests to access or delete data. Privacy questions use the same public support address.

12. Availability and Liability

AI outputs can contain errors and must be reviewed before use. The service is provided as available, without a guarantee of a specific result or generation time. To the extent permitted by applicable law, we do not accept liability for indirect losses. Nothing here limits rights or liability that applicable law does not allow us to limit.

13. Suspension and Termination

We may refuse requests or restrict or terminate service for serious abuse, fraud or legal requirements. You may request account closure or deletion at support@sevli.app. Any refund or data-retention duties are handled under applicable law and the policies linked above; canceled subscriptions and expired credits are not the same as account deletion.

14. Changes and Disputes

We may update these terms, recording the effective date and providing notice of material changes. These terms are governed by the applicable laws of China, without excluding mandatory consumer and privacy protections applicable to you. For a service or billing dispute, first contact support so we can investigate; this does not prevent you from exercising statutory complaint or dispute rights.
