WallKoo Terms of Use

  • Version: v1.0
  • Updated: July 21, 2026
  • Effective: July 21, 2026

1. Parties and Scope

  1. WallKoo is an AI wallpaper generation and sharing service operated by the WallKoo team (hereinafter referred to as “WallKoo,” the “Operator,” “we,” or “us”).
  2. This Agreement applies to the WallKoo website, generation tools, public wallpaper library, credit purchases, downloads, favorites, “Make Similar,” and any other feature that expressly refers to this Agreement (collectively, the “Services”).
  3. Our contact email is [email protected]. Notices, complaints, appeals, and other communications under this Agreement may be sent through that address or the in-service channels specified here.
  4. WallKoo serves users worldwide, but only where the relevant Services and content are lawful in the user’s location.

2. Acceptance

  1. When creating an account for the first time through an email verification code or Google sign-in, you confirm that you have read and accepted this Agreement and the Privacy Policy. We retain the accepted text version, account, time, and necessary verification records.
  2. If you do not agree, you may continue browsing public pages that do not require sign-in, but you may not register, generate content, purchase credits, or use other account-only features.
  3. Permission to publish reference images, any future model-training permission, and other matters that legally require separate consent are not combined with general acceptance of this Agreement.

3. Eligibility

  1. You must be at least 18 and have legal capacity to enter this Agreement to register, generate wallpapers, or purchase credits.
  2. Signed-out visitors may access public pages, but WallKoo is not directed to minors and does not allow minors to register, generate, or purchase credits.
  3. You must ensure that your use, uploads, downloads, and publication of generated results comply with local law. You may not use a feature or content in a region where it is prohibited.

4. Accounts and Security

  1. WallKoo supports email-code and Google sign-in. You must provide valid information and keep your account details current.
  2. Public works display the name and avatar currently in your WallKoo profile. These may initially come from Google sign-in and can be replaced in your profile. Your email, Google account identifier, and payment details are not made public merely because a work is public.
  3. Your account is personal. You may not sell, rent, transfer, lend it, or share login codes.
  4. You must reasonably secure your email, credentials, and devices. Report account misuse promptly to [email protected]. If you report promptly and the unauthorized act did not result from your intent or gross negligence, we will not automatically hold you responsible solely because it occurred through your account.
  5. You may not use scripts, bots, or other means to bypass the normal interface, credit deductions, access controls, or rate limits; scrape non-public data; disrupt the Services; insert malicious code; probe or exploit vulnerabilities; impersonate others; or perform destructive testing. Normal browsing, lawful search indexing, and APIs or automation expressly authorized by us are unaffected.
  6. Please privately report good-faith security findings to [email protected]. We will not treat the report itself as a malicious attack when testing was no broader than necessary, did not harm or obtain unrelated data, did not exploit the issue for gain, was not disclosed prematurely, and allowed reasonable remediation time.

5. Services and AI Characteristics

  1. WallKoo may provide static and live wallpapers, titles, and related display features based on prompts, reference images, models, dimensions, duration, and other parameters. Available features and models are those shown in the Services at the time.
  2. AI generation is probabilistic. The same input may produce different results, and results may be inaccurate, incomplete, unexpected, similar to others, or contain unforeseen elements.
  3. We do not guarantee that any result is copyrightable, exclusive, non-infringing, fit for a purpose, or usable on every device and application. Review results before publishing, using, or relying on them.
  4. Models are supplied by WallKoo or third parties and may be replaced, paused, or retired for maintenance, provider changes, compliance, or other reasons. Purchased credits are not reduced merely because a particular model is retired.
  5. WallKoo may reasonably maintain, upgrade, and troubleshoot the Services. Credits for tasks that fail because of WallKoo or a generation provider are returned under Section 7.

6. Public, Private, and Reference Images

  1. Generation tasks are public by default. You may change a task to private before submission or change a work’s status later in your library.
  2. A public work may expose its result, thumbnail, title, original prompt, original reference image, model, dimensions or aspect ratio, necessary publication time, download count, and your WallKoo name and avatar. Search engines may index it, and others may download, cache, screenshot, share, or use it with WallKoo’s “Make Similar” feature.
  3. Publishing a reference image lets other users view it on WallKoo and use it with “Make Similar.” You must have authority to grant that permission.
  4. “Private” only means the work is excluded from WallKoo’s public gallery, public work page, and other public in-service entry points. It does not mean confidential storage. Anyone holding an existing CDN URL may still access, save, or forward the file. Do not use private mode for confidential or highly sensitive materials.
  5. After you make a work private or delete it, WallKoo stops new public display and authorized use in the Services, but cannot retrieve copies lawfully downloaded earlier or ensure the immediate disappearance of search or browser caches, screenshots, or derivative content made by others.

7. Credits, Payment, and Refunds

  1. Credits are non-monetary units usable only for WallKoo generation services. They are not a wallet balance or deposit, cannot be transferred, withdrawn, redeemed for cash, or earn interest.
  2. Credit packs are one-time purchases, not subscriptions, and do not renew automatically. Purchases currently settle in U.S. dollars; quantities, prices, and estimated uses are shown on the purchase and checkout pages.
  3. Purchased credits do not expire while the account and Services remain active. Free, promotional, gifted, or compensatory credits may expire if disclosed before or when issued.
  4. Exchange differences, cross-border charges, and other issuer or payment-institution fees are between you and that institution. Prices include taxes only when checkout expressly says so; we may calculate or collect taxes when legally required.
  5. WallKoo provides ordinary order or payment records but does not promise VAT invoices or other tax documents for a particular jurisdiction unless mandatory law requires them.
  6. Top-ups are generally final and are not refunded for non-use, a change of mind, subjective dissatisfaction, or unmet expectations. Payment mistakes, unauthorized payments, missing credits, permanent service shutdown, materially adverse changes to purchased benefits, and mandatory legal rights are handled under this Agreement.
  7. If generation fails because of WallKoo or a model provider, deducted credits return automatically; cash is not automatically refunded. A successful result that subjectively disappoints you is not a failed generation.
  8. After a cash refund is approved, we may remove the corresponding unused credits. Provider fees may be deducted only when lawful and disclosed in advance.
  9. Future price changes apply only to later purchases and do not reduce credited balances.
  10. We may temporarily freeze related credits during a chargeback, reversal, or payment dispute. After a successful chargeback, we may remove credits; if already spent, the account may have a negative balance and generation may be restricted until resolution. The same payment cannot be refunded twice through both WallKoo and the payment provider.
  11. When you voluntarily close your account, all remaining paid and free credits lapse without an automatic refund, except where this Agreement expressly says otherwise or mandatory law requires it.

8. Rights in Inputs and Results

  1. You retain your existing rights in prompts, reference images, and other inputs. You represent that you have all rights or lawful permissions needed to submit, process, publish, and license them, without infringing intellectual property, privacy, image, reputation, or other rights.
  2. To the extent recognized by applicable law, you hold any rights that may arise in generated results. WallKoo does not claim ownership of results but does not guarantee their copyrightability, originality, or exclusivity.
  3. For private content, you grant WallKoo a worldwide, non-exclusive, royalty-free license limited to what is necessary to provide the Services: receiving, storing, copying, reformatting, sending to generation providers, generating titles, displaying to you, safety and quality review, troubleshooting, complaint handling, and legal compliance.
  4. For public content, you additionally grant WallKoo a worldwide, non-exclusive, royalty-free license to host, copy, transform, publicly display, distribute, enable downloading, promote WallKoo, and support “Make Similar.” WallKoo may give providers and users of relevant features the permissions necessary for those purposes.
  5. When public content becomes private or is deleted, that license ends for new public display, promotion, and “Make Similar,” without retroactively affecting lawful uses, downloads, caches, or copies already made.
  6. Unless you separately grant optional, revocable consent that is off by default, WallKoo will not use your prompts, reference images, or results to train or fine-tune models or authorize service providers to use them for their own training. Public content does not equal training consent.

9. Visitor License for Public Wallpapers

  1. Visitors receive a personal, non-exclusive, non-transferable, non-commercial license to download public WallKoo wallpapers and set them as wallpaper on personal devices.
  2. Without separate written authorization, visitors may not:
    • sell, rent, or otherwise commercialize public wallpapers;
    • redistribute them as a stock library, wallpaper pack, dataset, or other collection;
    • falsely claim authorship or exclusive rights;
    • use them as a trademark, service mark, or source identifier;
    • remove or alter AI labels that law requires to remain; or
    • use them in a way that infringes others’ rights or violates this Agreement.
  3. “Make Similar” is a separately permitted WallKoo feature. It conveys no ownership in the original work or reference image and no off-platform commercial license.
  4. If a public item becomes unavailable after a complaint, deletion, or status change, previously lawful personal-use copies are unaffected, but remain subject to this Section and applicable law.

10. AI-Generated Content Labels

  1. WallKoo appropriately identifies AI-generated content on public pages and retains visible labels and machine-readable implicit labels or provenance metadata required by applicable rules in exported images or videos.
  2. If WallKoo offers a clean file without a visible label, the user must actively request it and confirm responsibility for later labeling and use before receiving it. We keep records of the recipient, file, confirmation version, and time for at least six months, or longer if required by law.
  3. Users may not maliciously remove, alter, forge, or conceal legally required AI labels. When republishing, distributing, or using content where the public could be confused, users must meet applicable labeling duties and must not deliberately present AI-generated content as a real record or wholly human creation.

11. Content and Conduct Rules

You may not use WallKoo to submit, generate, publish, download, distribute, or help create:

  1. explicit sexual or obscene content, non-consensual intimate content, or any sexual or sexualized content involving minors;
  2. unauthorized or harmful uses of a real person’s likeness, including impersonation, false endorsement, sexualization, fraud, harassment, or misleading fabricated depictions;
  3. material assistance for crime, or promotion, recruitment, or funding of terrorism or violent extremism;
  4. hatred, discrimination, or violence based on protected traits such as race, ethnicity, nationality, religion, sex, sexual orientation, or disability;
  5. encouragement or instructions for suicide or self-harm, or severe harassment, threats, or harm directed at an identifiable person;
  6. fraud, phishing, forged credentials, malware, account theft, security bypass, or other deception;
  7. unauthorized disclosure of another person’s address, contact details, credentials, identification documents, or other private information;
  8. actionable instructions involving weapons, drugs, or other dangerous conduct that directly enable serious harm;
  9. infringement of intellectual property, privacy, image, reputation, or other lawful rights;
  10. deliberate public deception through fabricated voting information, emergency notices, official statements, or similar material; or
  11. content or conduct that violates applicable law, public order, or another part of this Agreement.

Lawful, non-explicit artistic, medical, or educational nudity may be generated but is excluded from the public gallery by default. Lawful fictional violence and historical, newsworthy, educational, medical, religious, political, or counter-hate content are not categorically banned by subject alone; WallKoo may still restrict gallery or recommendation placement based on presentation, risk, and the public-display context.

12. Content Review, Enforcement, and Appeals

  1. For safety, quality evaluation, feature testing, troubleshooting, complaints, and legal duties, WallKoo may automatically inspect public and private inputs and results, and authorized personnel may sample or review them where necessary under access controls. “Private” does not mean WallKoo cannot access content.
  2. Human access must remain limited to those purposes and not personal curiosity. Review alone does not permit private content to be used for model training or marketing.
  3. Automated systems may reject generation, flag content, temporarily block publication, or refer content for human review. Accounts may be immediately restricted to control risks involving child sexual content, malicious code, obvious fraud, or an active security attack.
  4. We may proportionately refuse generation, unpublish or delete content, limit features, suspend accounts, or terminate accounts. Ordinary violations generally receive a chance to correct where reasonable; serious, urgent, or repeated violations may be handled immediately.
  5. Permanent bans, forfeiture of credits, and other major final actions are generally confirmed by a person; emergency restrictions may precede review.
  6. Unless prohibited by law or a notice would impede an investigation or expose security measures, we explain the principal reason. You may appeal for human review within 30 days of notice at [email protected].
  7. Credits remaining when an account is terminated for a serious violation are not refunded unless mandatory law requires it.
  8. We do not disclose specific rules, thresholds, or model parameters that would materially help bypass review.

13. Intellectual Property and Other Rights Complaints

  1. A rights holder who believes WallKoo content infringes intellectual property or other lawful rights may complain at [email protected]. The complaint should include:
    • the rights holder’s true identity and valid contact details;
    • proof of the right or authorization;
    • an exact link or other location information for the allegedly infringing content;
    • preliminary evidence of infringement;
    • a statement that the material is truthful, accurate, and submitted in good faith; and
    • a signature or other verifiable confirmation.
  2. Based on preliminary evidence and the nature of the Services, we may unpublish, restrict, delete, or take other necessary action and forward the complaint to the uploader. Sensitive information unrelated to the dispute may be redacted.
  3. The uploader may counter-notify with true identity and contact information, authorization or preliminary evidence of non-infringement, and a truthfulness statement.
  4. We forward the counter-notice to the complainant and explain that they may complain to the competent authority or sue in a court with jurisdiction. If we receive no proof of such a filing within 15 days after the complainant receives it, we may restore the content unless it otherwise violates rules, restoration creates a concrete risk, or applicable law provides otherwise.
  5. A person making a false or malicious complaint is responsible for resulting harm. Accounts engaged in repeat infringement or repeated malicious rights violations may be terminated.

14. Deleting Works and Closing Accounts

  1. You may delete a work from your library or submit a verified closure request through the dedicated account-closure page.
  2. After deletion, we immediately stop public display and plan to permanently delete the result, thumbnail, and relevant reference images from active storage within 30 days. Isolated backups expire through their rotation cycle. Records needed for disputes, complaints, or legal duties are excepted.
  3. Once closure is confirmed, the account is disabled, its works stop being publicly displayed, remaining credits are handled under Section 7, and deletion or anonymization begins.
  4. Prior downloads, screenshots, search caches, and lawful derivative content may remain. Closure or deletion does not require WallKoo to retrieve copies from third-party devices.
  5. Orders, credit ledgers, refunds, chargebacks, anti-fraud, dispute, security, review, and consent records may be retained under the Privacy Policy and applicable law.

15. Service Restrictions, Termination, and Permanent Shutdown

  1. We may temporarily restrict the Services for maintenance, faults, provider outages, force majeure, security risks, legal requirements, or other reasonable grounds, with notice where feasible. Credits for failed generation are returned under Section 7.
  2. Accounts violating this Agreement may be restricted or terminated under Section 12.
  3. If WallKoo plans a permanent shutdown, where feasible we give at least 30 days’ notice so users can spend credits and download existing works during the transition.
  4. After permanent shutdown, unusable paid credits are refunded in proportion to their original purchase amount. Free, promotional, gifted, and compensatory credits have no cash value. Exceptions may apply to serious violations, fraud, or legally required immediate action, without affecting mandatory rights.

16. Third-Party Services

  1. WallKoo uses services including Google, Waffo Pancake, Cloudflare, and EvoLink for sign-in, email, payment, storage, generation, title processing, app hosting, and databases.
  2. Third-party availability, processing locations, and independent conduct are governed by their terms and privacy policies. The Privacy Policy describes relevant purposes and data, and WallKoo uses reasonable efforts to select and manage providers.
  3. Using third parties does not itself release us from our duties under this Agreement or applicable law, but we cannot guarantee uninterrupted third-party service or the permanent availability of any model.

17. Service Assurances and Limits of Liability

This Section contains important terms about the scope of liability. Please read it carefully.

  1. Except for express promises here or otherwise required by law, WallKoo provides the Services as available and makes no warranty about AI-result accuracy, uniqueness, copyrightability, non-infringement, fitness for a purpose, or continued availability of a particular model.
  2. You are responsible for your inputs, publication choices, downloads, distribution, and use. This allocation does not remove WallKoo’s express duties concerning failed-task credits, data security, privacy, or other legal obligations.
  3. To the extent permitted by law, WallKoo is liable for evidenced, reasonably foreseeable, actual losses directly caused by its breach or fault. Liability for lost profit, lost opportunity, or other indirect or consequential loss will not be unreasonably expanded.
  4. This Agreement sets no single monetary liability cap and excludes no liability that law prohibits limiting, including liability for intent or gross negligence, personal injury, fraud, and statutory personal-information protection.

18. Changes to This Agreement

  1. Editorial corrections and updates to links or contact information that do not affect user rights may take effect on publication without renewed acceptance.
  2. Material changes involving prices, credit rights, public licenses, content review, personal-information uses, or user responsibilities are generally notified by in-service message or email at least 7 days in advance with a summary. We aim for 30 days’ notice for materially adverse changes.
  3. A change required immediately by urgent security risk or law may take effect at once, with prompt notice where feasible.
  4. After a material change takes effect, users must actively accept it again to continue generating, purchasing credits, or publishing works. Continued browsing of public pages is not acceptance.
  5. A user who rejects new terms may sign in, download or delete existing works, and close the account during a 30-day transition, but may not continue generating, purchasing, or publishing.
  6. If new terms materially reduce purchased rights, a user closing the account during the transition may request a proportional refund for affected unused paid credits. Ordinary policy changes remain subject to the no-refund rule for voluntary closure.

19. Change of Operator or Business

  1. The Operator may transfer the WallKoo business and this Agreement as a whole to a company the Operator establishes or controls, or to a lawful successor to the WallKoo business.
  2. The successor must continue the then-current obligations for credits, content deletion, user terms, and data protection. We generally give at least 30 days’ notice of the new operator, contact details, effective date, and important changes.
  3. A successor proposing new personal-information uses, model training, advertising profiles, or another material change must obtain renewed consent under Section 18.
  4. We will not sell personal information apart from the WallKoo business as a standalone user list or data asset.
  5. If bankruptcy, court order, or other circumstances prevent complete advance notice, we notify users as soon as law permits.

20. Notices, Disputes, and Miscellaneous Terms

  1. We may send notices through the email linked to your account, in-service notices, relevant feature pages, or website announcements. Keep your email available.
  2. The parties may first try to resolve disputes through [email protected]. This Agreement does not designate one country’s or region’s law as exclusively governing; applicable law and courts with jurisdiction are determined under mandatory rules effective when the dispute arises.
  3. If a provision is invalid or unenforceable, the remaining provisions continue, and the invalid part is handled as close to its original purpose as law permits.
  4. A delay in exercising a right is not a waiver.
  5. Questions about this Agreement, accounts, payments, content enforcement, rights complaints, or security may be sent to [email protected].
