(2) The Company uses artificial intelligence technology to automatically analyze and edit Original Content in the course of providing the Service. In accordance with the AI Framework Act, the Company discloses in advance that the Service operates on the basis of artificial intelligence technology. An Output is the result of analyzing, selecting and editing the Original Content uploaded by the Member; the Company does not use artificial intelligence to newly generate video or audio that is not present in the Original Content. However, because Outputs are automatically edited and processed, the editing result may be composed in a manner that differs from the Member’s intent or from actual facts.

(3) The Company removes location information contained in Original Content (all location metadata recorded in the file, including GPS coordinates) during upload processing and does not use or retain it for any purpose. The Company does not provide any feature that uses location information.

(4) The Company may entrust part of the processing necessary to provide the Service to domestic or overseas cloud service providers. Specific matters concerning such entrustment and the transfer of personal information abroad are set out in the Privacy Policy.

(5) During the beta period, the Company may restrict certain features or provide them in an in-preparation state, and shall specify within the Service the scope of features that are provided, restricted or in preparation. The Company shall give advance notice of the end of the beta period, and where a feature for which a Member has paid becomes restricted and unusable, the Company shall return the corresponding Credits or provide equivalent compensation.

Article 12-2 (YouTube Upload Feature)

(1) The Company provides a feature that enables a Member to upload Outputs to the Member’s own YouTube channel. Use of this feature is at the Member’s option, and a Member who does not use it faces no restriction on the use of the rest of the Service.

(2) This feature is provided using YouTube API Services. By using this feature, a Member agrees to be bound by the YouTube Terms of Service (https://www.youtube.com/t/terms). The Google Privacy Policy (https://www.google.com/policies/privacy) applies to personal information processed by Google in connection with this feature.

(3) A Member may use this feature after linking their YouTube account to the Service through Google’s authentication procedure, and at the time of linking the Company obtains the following permissions.

(7) The publication, visibility, management and deletion of videos uploaded to YouTube, and related matters, are governed by YouTube’s terms and policies as between the Member and YouTube, and the Company is not involved in them. Deleting an Output within the Service, unlinking the YouTube account or withdrawing membership does not affect videos already uploaded to YouTube; such videos must be modified or deleted by the Member directly on YouTube.

(8) The Member is responsible for the Outputs uploaded and for the upload information under paragraph (4), including the content of thumbnails and captions and the choice of license. Before uploading an Output as public or unlisted or scheduling its publication, the Member must confirm that consent has been obtained from the Depicted Individuals included in the Output. Where an Output includes background music, the Member must comply with the license scope under Article 15(4) and must not select a license that goes beyond that scope.

(9) A Member may unlink their YouTube account at any time on the settings screen within the Service, and may also revoke the Service’s access through the Google account security settings page (https://security.google.com/settings/security/permissions). The destruction of information upon unlinking or revocation of access is governed by Article 9 of the Privacy Policy.

(10) The Company shall not be liable for any failure or delay of an upload, any failure to apply upload information, or any restriction of visibility that occurs without the Company’s willful misconduct or negligence, such as a failure of YouTube, a change to or discontinuation of YouTube’s terms, policies or API, daily usage limits, review status (including where a video remains private after its scheduled publication time), or action taken by YouTube with respect to the Member’s account.

The Company shall notify the Member seven (7) days before expiry of the retention period.

(4) A Member must download and separately store Outputs and Original Content before the retention period expires; content destroyed after expiry of the retention period cannot be recovered. The Company shall provide notice of this within the Service and on the project screen.

A Member must review the license scope posted within the Service before generating an Output, and may not:

The video and audio themselves are not used in such analysis.

(2) The mere fact that a Member recorded or possesses a video does not entitle the Member to exercise, on behalf of a Depicted Individual, that individual’s rights of likeness and voice or their right to informational self-determination. Such rights belong exclusively to the Depicted Individual, and the consent of the Depicted Individual (or, in the case of a minor, of their legal representative) is required in order to provide that individual’s personal information to a third party or to use it commercially.

(3) Requests under paragraph (1) may be submitted to heimlog@heimdex.co.

Article 19 (Prevention of Distribution of Unlawfully Recorded Material)

(1) The Company operates reporting and deletion procedures to prevent the distribution of unlawfully recorded material as required by applicable law.

However, in urgent cases, notice may be given after the fact.

(3) A Member may object to a measure under paragraphs (1) and (2) by writing to heimlog@heimdex.co within fifteen (15) days from the date of receipt of the notice, and the Company shall immediately restore use of the Service where the objection is found to be justified.

Article 21 (Deletion and Retention of Member Content)

(1) A Member may delete Original Content and Outputs at any time using the functions within the Service.

(2) Content deleted by a Member is destroyed without delay from the Service and its operational databases, and any copies remaining in backup storage are destroyed by an irrecoverable method within sixty (60) days in accordance with the backup rotation cycle. However, datasets already provided to third parties as described in Article 6(3) of the Privacy Policy are excepted.

(3) Paragraphs (1) and (2) apply equally where a Member terminates the service agreement.

(4) Deleting an Output within the Service does not delete videos already uploaded to YouTube; this is governed by Article 12-2(7).

Article 22 (Access to Data for Handling Inquiries and Disputes)

(1) The Company may access a Member’s Original Content and Outputs to the minimum extent necessary to handle the Member’s inquiries, error reports, objections, reports of rights infringement or disputes.

(3) In order to restrict the right of withdrawal under item 1 of paragraph (2), the Company shall clearly indicate that fact on the pre-payment screen and on the screen preceding the start of analysis, and shall together provide trial goods or the equivalent by the methods prescribed in Article 21-2 of the Enforcement Decree of the Act on the Consumer Protection in Electronic Commerce, Etc., such as by providing a low-resolution preview of the Output. Where the Company fails to take such measures, the right of withdrawal is not restricted.

(4) Notwithstanding paragraphs (1) and (2), where the contents of the Service differ from those indicated or advertised or the contract has been performed differently from its terms, a Member may withdraw their subscription within three (3) months from the date of receipt of provision, or within thirty (30) days from the date on which the Member became aware or could have become aware of that fact.

Section 2 (Eligibility)

(1) You must be at least fourteen (14) years old to register for the Service. The Service is not directed to children under the age of thirteen (13).

(2) If you are under the age of majority in your state of residence, you may use the Service only with the involvement and consent of your parent or legal guardian, who must review and agree to these Terms on your behalf, and any purchase of a paid service requires the consent of your parent or legal guardian. For U.S. Users, this paragraph applies in place of Article 7(2).

(3) You represent that you are not prohibited from using the Service under the laws of the United States or any other applicable jurisdiction.

Section 3 (Electronic Communications)

You consent to receive agreements, notices, disclosures and other communications from the Company electronically, including by email to the address registered to your account and by notice within the Service, and you agree that such electronic communications satisfy any legal requirement that such communications be in writing.

Section 4 (Subscriptions, Automatic Renewal and Refunds)

(1) A recurring subscription renews automatically at the end of each subscription period for a period of the same length, and the fee then in effect is charged to your designated payment method, unless you cancel before the renewal date. The price, billing frequency and renewal terms are displayed before you subscribe, and you must affirmatively agree to them before you are first charged.

(2) You may cancel a recurring subscription at any time online through the account settings within the Service. Cancellation takes effect at the end of the current subscription period, and you may continue to use the paid features until then.

(4) The refund terms set out in Article 25 apply to U.S. Users as the Company’s refund policy. References in Article 25 to Korean statutes describe the basis of that policy and do not reduce any right you have under applicable U.S. law.

(5) Payments may be processed by a third-party payment processor or reseller, whose terms and privacy policy may also apply to your payment. Prices do not include applicable sales, use or similar taxes unless stated otherwise.

Section 5 (Recording, Privacy and Publicity Laws)

In addition to your obligations under Article 17, you are solely responsible for complying with all laws that apply to the recording, uploading and publication of your Original Content and Outputs, including laws governing the recording of conversations (some of which require the consent of all parties), privacy laws and rights of publicity.

(4) The Company will, in appropriate circumstances, terminate the accounts of Members who are repeat infringers.

Section 7 (Disclaimer of Warranties)

TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE SERVICE, INCLUDING OUTPUTS AND THE YOUTUBE UPLOAD FEATURE, IS PROVIDED “AS IS” AND “AS AVAILABLE,” AND THE COMPANY DISCLAIMS ALL WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE AND NON-INFRINGEMENT. THE COMPANY DOES NOT WARRANT THAT THE SERVICE WILL BE UNINTERRUPTED OR ERROR-FREE, THAT OUTPUTS WILL BE ACCURATE OR MEET YOUR EXPECTATIONS, OR THAT CONTENT WILL NOT BE LOST. SOME JURISDICTIONS DO NOT ALLOW THE EXCLUSION OF CERTAIN WARRANTIES, SO SOME OF THE ABOVE EXCLUSIONS MAY NOT APPLY TO YOU.

Section 8 (Limitation of Liability)

(1) TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE COMPANY SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, DATA OR GOODWILL, ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE, EVEN IF THE COMPANY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

(2) TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, THE COMPANY’S TOTAL LIABILITY ARISING OUT OF OR RELATING TO THESE TERMS OR THE SERVICE SHALL NOT EXCEED THE GREATER OF (A) THE AMOUNTS YOU PAID TO THE COMPANY FOR THE SERVICE DURING THE TWELVE (12) MONTHS BEFORE THE EVENT GIVING RISE TO THE LIABILITY AND (B) ONE HUNDRED U.S. DOLLARS (US$100).

To the extent permitted by applicable law, you agree to indemnify and hold harmless the Company and its officers, directors and employees from and against any claims, damages, losses and expenses (including reasonable attorneys’ fees) arising out of (a) your Original Content, Outputs or upload information, (b) your breach of these Terms, or (c) your violation of any law or of the rights of any third party, including any Depicted Individual. The Company will notify you of any such claim and may participate in the defense with counsel of its choice.

Section 10 (Dispute Resolution by Binding Individual Arbitration)

PLEASE READ THIS SECTION CAREFULLY. IT REQUIRES YOU AND THE COMPANY TO RESOLVE MOST DISPUTES THROUGH BINDING INDIVIDUAL ARBITRATION AND WAIVES THE RIGHT TO A JURY TRIAL AND TO PARTICIPATE IN A CLASS ACTION. YOU MAY OPT OUT AS DESCRIBED IN PARAGRAPH (7).

(1) Informal resolution. Before starting an arbitration or court proceeding, you and the Company agree to try to resolve any dispute informally. The party raising the dispute must send a written notice describing the dispute and the relief sought, to the Company at heimlog@heimdex.co or to you at the email address registered to your account. If the dispute is not resolved within sixty (60) days after the notice is received, either party may begin arbitration.

(2) Agreement to arbitrate. Except as provided in paragraph (3), any dispute, claim or controversy between you and the Company arising out of or relating to these Terms or the Service (a “Dispute”) shall be resolved by final and binding individual arbitration. This Section is governed by the Federal Arbitration Act, 9 U.S.C. § 1 et seq. The arbitrator has authority to resolve any question regarding the interpretation, applicability or enforceability of this Section, except as provided in paragraph (8).

(3) Exceptions. Either party may (a) bring an individual claim in small claims court if the claim qualifies and remains in that court, or (b) seek injunctive or other equitable relief in court to prevent the infringement or misappropriation of its intellectual property rights.

(4) Rules and procedure. The arbitration will be administered by the American Arbitration Association (“AAA”) under its Consumer Arbitration Rules then in effect, available at www.adr.org. The arbitration will be conducted by video conference, telephone or written submissions unless the arbitrator determines that an in-person hearing is necessary, in which case the hearing will take place in the county of your residence. Filing, administration and arbitrator fees are governed by the AAA’s rules, and the Company will pay the fees that those rules allocate to the business. The arbitrator may award the same individual relief that a court could award, but only in favor of the individual party seeking relief and only to the extent necessary to provide relief warranted by that party’s individual claim.

(5) Class action and jury trial waiver. YOU AND THE COMPANY AGREE THAT EACH MAY BRING CLAIMS AGAINST THE OTHER ONLY IN AN INDIVIDUAL CAPACITY AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY PURPORTED CLASS, COLLECTIVE, CONSOLIDATED OR REPRESENTATIVE PROCEEDING. YOU AND THE COMPANY WAIVE ANY RIGHT TO A TRIAL BY JURY.

(6) Mass arbitration. If twenty-five (25) or more similar demands for arbitration are filed against the Company by or with the assistance of the same or coordinated counsel, the AAA’s Mass Arbitration Supplementary Rules apply, and the parties agree that such demands may be administered in batches in accordance with those rules.

(7) Opt-out. You may opt out of this agreement to arbitrate by sending an email to heimlog@heimdex.co within thirty (30) days after you first accept these Terms (or, if you registered before the effective date of this Annex, within thirty (30) days after that effective date), stating your name, the email address registered to your account and that you opt out of arbitration. If you opt out, paragraphs (2) and (4) to (6) do not apply to you, and Disputes will be resolved in accordance with Section 11.

(8) Severability. If the class action waiver in paragraph (5) is found unenforceable with respect to any claim or request for relief, that claim or request (and only that claim or request) shall be severed and brought in court in accordance with Section 11, and shall be stayed pending completion of any individual arbitration.

(9) Changes. If the Company changes this Section after you have accepted it, the change will not apply to any Dispute of which the Company received notice before the change took effect, and you may reject the change by emailing heimlog@heimdex.co within thirty (30) days after it takes effect.

Section 11 (Governing Law and Venue)

(1) Article 29(2) and (3) do not apply to U.S. Users. These Terms and any Dispute are governed by the Federal Arbitration Act and, to the extent not preempted, the laws of the State of Delaware, without regard to its conflict-of-laws rules. This choice of law does not deprive you of the protection of any mandatory consumer protection laws of your state of residence.

(2) Any Dispute that is not subject to arbitration under Section 10 shall be brought in the state or federal courts located in the State of Delaware, and you and the Company consent to the personal jurisdiction of those courts, except where the laws of your state of residence entitle you to bring the action in the courts of that state.

(3) To the extent permitted by applicable law, any claim arising out of or relating to these Terms or the Service must be brought within one (1) year after the claim arises.

Section 12 (Export Controls and Sanctions)

You may not use the Service if you are located in, or ordinarily resident in, a country or region subject to comprehensive U.S. sanctions, or if you are identified on any U.S. government list of prohibited or restricted parties. You agree to comply with all applicable export control and sanctions laws in connection with your use of the Service.
