Agreement and eligibility
By accessing markandera.app, uploading a photo, creating an account or purchasing a plan, you agree to these Terms and our Privacy Policy. If you do not agree, do not use the service.
You must be legally able to enter this agreement and follow the laws and organizational policies that apply to you. If you use Mark & Era for an organization, you represent that you have authority to accept these Terms on its behalf.
Operator and contact details
Mark & Era is operated through markandera.app. Product, account, billing, privacy and legal inquiries can be sent to the support team at support@markandera.app.
The Mark & Era service
Mark & Era helps users submit a single JPG, PNG or WEBP photo and receive an AI-assisted research starting point. Depending on the image, the result may include a likely match, collectible category, estimated era, possible origin, estimated market range, evidence clues, possible lookalikes, risk flags and a suggested next photo.
The service is a visual research utility. It is not a formal appraisal, authentication certificate, insurance valuation, provenance service, laboratory analysis, conservation report, guaranteed sale-price service or certified records system. Features, limits, supported browsers and third-party model availability may change.
License and ownership
Subject to these Terms and the applicable plan, we grant you a limited, revocable, non-exclusive, non-transferable license to use the released website for personal or internal business purposes. Mark & Era and its software, design, branding, documentation and other service materials remain owned by us or our licensors.
Except where applicable law expressly permits it, you may not copy, modify, distribute, sell, rent, sublicense, reverse engineer, bypass licensing or usage controls, or create a competing service from protected parts of Mark & Era.
Your photos and responsibilities
You retain any rights you have in photos you submit. You are responsible for having permission to upload, process, retain and share the images and information you provide. Do not upload images that contain private information, another person's likeness, confidential material or content you are not authorized to process.
You are responsible for reviewing important results. Lighting, blur, distance, background objects, similar items, model limitations, missing marks or missing physical inspection can affect a research result. Keep the original item and seek qualified help when accuracy, evidence, authenticity or value matters.
Accounts and security
You are responsible for keeping your account, browser profile, device and session secure. Provide accurate account and billing information, do not share paid access outside permitted use, and notify support@markandera.app if you suspect unauthorized account or payment activity.
Free access, paid plans and billing
The Pricing page describes current monthly subscriptions and one-time credit packs, including the credits and usage access associated with each plan. Prices are shown in USD before applicable taxes unless checkout says otherwise. Paid access begins after payment confirmation.
Monthly subscriptions renew automatically every 30 days at the interval and price disclosed at checkout until canceled. Credit packs are one-time purchases and do not renew automatically. Canceling a subscription stops future renewal and normally leaves access active through the paid period. Refund requests are governed by our Refund Policy and non-waivable consumer law.
Acceptable use
- Do not upload, process, retain or share photos or information without authorization.
- Do not use Mark & Era to violate privacy, confidentiality, intellectual-property, employment, records, sanctions or other laws.
- Do not introduce malware, evade security controls, impersonate another person, abuse authentication or interfere with the service.
- Do not use automated activity to overload markandera.app, api.markandera.app, our payment or licensing systems, the image-research provider or third-party services.
- Do not resell access, share a license improperly, bypass plan limits or misrepresent Mark & Era as a formal appraisal, authentication, laboratory or professional authority.
Third-party services
Mark & Era relies on third-party products such as hosting, authentication, payment, analytics, advertising and image-research services. Their services are governed by their own terms and can change, restrict, suspend or discontinue functionality without our control. Mark & Era is an independent product and is not affiliated with or endorsed by Google, Apple, OpenAI, any auction house or any museum or professional appraisal organization.
Availability and changes
We may add, change, limit, suspend or discontinue features, plans, integrations or access when reasonably necessary for product development, security, legal compliance, third-party changes or business operations. We aim to provide reasonable notice of material changes affecting an active paid plan when practical, but uninterrupted availability is not guaranteed.
Suspension and termination
You may stop using the service at any time. We may restrict, suspend or terminate access for nonpayment, fraud, abuse, security risk, legal necessity or material violation of these Terms. Provisions that should reasonably survive termination, including ownership, payment obligations, disclaimers, liability limits and dispute-related terms, continue to apply.
Disclaimers
To the extent permitted by law, Mark & Era is provided on an as-is and as-available basis. We do not warrant uninterrupted operation, compatibility with every browser or device, perfect reproduction of every visual feature, a correct result for every item, or suitability for a particular scientific, legal, regulatory, tax, insurance, safety or valuation requirement. These disclaimers do not exclude warranties or rights that cannot legally be excluded.
Limitation of liability
To the extent permitted by law, Mark & Era and its operators will not be liable for indirect, incidental, special, consequential, exemplary or punitive damages, or for loss of content, records, revenue, profits, goodwill or business opportunity arising from use of the service. To the extent permitted by law, aggregate liability relating to the service will not exceed the amount you paid to Mark & Era during the 12 months before the event giving rise to the claim.
Some jurisdictions do not allow certain exclusions or limitations, so parts of this section may not apply to you.
Changes, questions and disputes
We may update these Terms by posting a revised version and date on markandera.app. Continued use after the effective date means acceptance where permitted by law. Before starting a formal dispute, please contact support@markandera.app and provide enough information for us to try to resolve the issue. Nothing in these Terms limits rights or remedies that cannot be waived under applicable law.
