The terms,in plain words first.

Effective date: 2 October 2026

These Terms of Service govern the global edition of Ramosa, including its desktop application, the website at https://ramosa.app, and the account and AI services we provide in connection with it (together, the “Service”). They explain your rights and responsibilities, how subscriptions work, and our responsibilities to you.

1Who provides Ramosa

The Service is provided by Shanghai Ottera Internet Technology Co., Ltd., a company established in the People's Republic of China (“Ottera”, “we”, “us”, or “our”). Our registered address is Room 581, Building 2, No. 350 Xianxia Road, Changning District, Shanghai, People's Republic of China. You may contact us at [email protected].

These Terms form an agreement between Ottera and the person or organization accepting them (“you”). By affirmatively accepting these Terms when registering or using a feature that requires acceptance, you agree to them. This includes continuing with a sign-in option whose screen states that continuing means you accept these Terms. If you act for an organization, you must have authority to bind it. If you do not agree, do not register for or use the Service.

Our Privacy Policy explains how personal information is handled. It is a privacy notice, not a blanket consent to every form of data processing. Our Refund Policy forms part of these Terms. A separately agreed written contract may supplement or replace provisions it expressly identifies. Mandatory rights under applicable law always remain available.

2Eligibility and your account

You must be at least 18 years old and legally capable of entering this agreement. You must provide accurate account information, keep your login email accessible, and protect your device, verification codes, and authentication credentials. If you sign in with a Google or Microsoft account, that provider authenticates you, and losing access to it can prevent you from signing in to Ramosa that way. Do not share an individual account in a way that permits unauthorized access to another person's information or circumvents a purchased plan.

Tell us promptly if you reasonably suspect unauthorized use. You are responsible for activity you authorize and for reasonable precautions within your control. You are not automatically responsible for activity caused by a failure of our security or by conduct for which applicable law makes us responsible.

Your Ramosa account is separate from any email account you connect. Signing in to Ramosa with Google or Microsoft identifies you only and does not connect or grant access to a mailbox. Deleting a Ramosa account does not delete your account with Google, Microsoft, or another email provider.

3What the Service does

Ramosa is an email client with tools for reading and sending email, organizing messages locally, searching, managing follow-up tasks, and using AI for functions such as classification, summaries, drafting, translation, and reply suggestions. The features available to you depend on the released application version, connected provider, plan, and supported region. A feature described as planned, in testing, or unavailable is not part of a paid entitlement unless the purchase description expressly says otherwise.

Ramosa stores its working email database and related local results on your device. AI features involve transmitting relevant content through our cloud relay and authorized AI service providers as explained in the Privacy Policy. Cloud account services also process account, security, subscription, and usage records. Ramosa is not an independent backup or long-term archival service, and signing in on another device does not by itself restore local drafts, settings, or other local-only information.

Local classification and archiving do not move or delete messages in your provider's mailbox. Sending a message is an action you initiate. Where supported, marking a message as read at the provider is performed only when the relevant setting is enabled and you take the corresponding action. An AI-generated draft or suggestion is not sent merely because it has been generated.

4Connecting email and other services

Connect only accounts you own or are authorized to use. Follow your email provider's terms and, for a work account, your organization's access and confidentiality rules. Grant only permissions you are willing and authorized to grant. A provider's consent screen may describe a permission more broadly than the actions Ramosa implements; the Privacy Policy explains our actual use.

You authorize the Service to carry out the email actions and processing you request or enable. Where your provider supports it, connecting a mailbox also registers the new-message notifications described in the Privacy Policy, so that your device can fetch new mail sooner. You may remove a connection and revoke authorization with the provider. Revocation stops further authorized access after it takes effect, but does not itself erase local copies, cancel a Ramosa subscription, or delete the Ramosa account. Instructions for these separate steps appear in the Privacy Policy.

Email providers and other third-party services operate independently. Their availability, limits, policies, and permission decisions may affect the Service. We remain responsible for our own obligations and for providers acting on our behalf to the extent required by law; this paragraph does not transfer those responsibilities to you.

5AI features and your decisions

AI outputs are probabilistic and may omit information, mistranslate a passage, misclassify a message, or generate an inaccurate statement. Check important messages, translations, factual statements, deadlines, recipients, and drafts before relying on them or sending them. Automated classification and suspicious-message screening cannot identify every important message or every threat.

You retain control over whether to act on an output. The Service is not a substitute for professional advice or for your independent judgment, and is not designed to be the sole control for emergency, medical, legal, financial, or other decisions where an error may cause serious harm. These limitations do not excuse a failure to provide the features and quality that we expressly promise or that law requires.

AI features stay off until you turn them on in the application, and you can turn them off again in Settings at any time. AI processing must follow the disclosed purposes and consent choices. These Terms do not authorize us or an AI provider to use your emails, prompts, or outputs to train general-purpose models. The more specific commitments in the Privacy Policy, including the Google Limited Use commitments, apply.

6Your content and our limited permission

“Your Content” means emails, attachments, drafts, instructions, and other material you make available through the Service. You and the relevant rights holders retain ownership of that material. We do not acquire ownership of your mailbox or correspondence.

You give us a limited, non-exclusive permission to process Your Content solely to provide the functions you request or enable, secure the Service, resolve a support request you authorize, and meet legal obligations. We may involve service providers only within the Privacy Policy's restrictions. This permission does not authorize advertising use, sale of email content, unrelated profiling, public distribution, or general-purpose model training. It ends when processing is no longer necessary for those purposes, subject to the disclosed retention rules and legal obligations. Removing an account does not recall messages you have already sent to recipients.

As between you and Ottera, to the extent legally possible, you own AI output generated for you. We assign any rights we may have in that output to you. This does not transfer third-party rights, guarantee copyright protection, or guarantee that other users will not receive similar output.

You must have a lawful basis and any necessary authority to use other people's information through the Service. Do not submit information in breach of a duty of confidence or a binding restriction on third-party AI processing. If your organization needs a data processing agreement or other special safeguards, contact us and put those arrangements in place before using the relevant processing for that purpose. These Terms alone are not a data processing agreement under Article 28 of the GDPR.

7License and acceptable use

While you comply with these Terms, we grant you a limited, non-exclusive, non-transferable license to install and use the released application for your own personal or internal business purposes within your plan. Ottera and its licensors retain rights in the software, design, branding, and documentation. Open-source components remain subject to their applicable licenses, which take priority for those components where required.

You must not use the Service to:

• access another person's account without permission, steal credentials, distribute malware, conduct phishing, send unlawful spam, or facilitate fraud;
• violate privacy, confidentiality, intellectual property, sanctions, or other applicable legal requirements;
• bypass authentication, quotas, payment requirements, or security measures, or disrupt other users or the infrastructure;
• resell or sublicense the Service, extract credentials, or use shared or automated accounts to evade plan restrictions; or
• reverse engineer or otherwise exploit the software except where applicable law permits this despite a contractual restriction, or where an applicable open-source license allows it.

Good-faith security research conducted lawfully and without accessing other users' data, disrupting the Service, or exceeding authorization is not prohibited merely because it identifies a weakness. Report security concerns to [email protected] and avoid including live credentials or unrelated private messages.

8Plans and usage allowances

We may offer free and paid plans. The pricing page and checkout identify the price, billing period, included features, and material limits that apply when you subscribe. Taxes and the currency and total amount payable are shown at checkout. We do not charge an unapproved overage merely because an allowance is exhausted.

AI allowances are shared across devices using the same account. Their measurement period may differ from your subscription billing period; where an allowance renews on a rolling seven-day basis, paying monthly does not create a monthly reset. The product and pricing disclosures explain applicable limits. AI may pause when an allowance is exhausted while other available email functions continue. Unused included allowances are not cash, do not accrue interest, and do not carry forward unless the offer expressly provides otherwise. This does not reduce refund rights.

We may apply proportionate technical limits to protect the Service from abuse. We will not use an undisclosed limit to materially reduce an already purchased entitlement. Material changes to paid features or allowances follow Sections 10 and 12.

9Purchases through Paddle

When checkout identifies Paddle as the merchant of record, Paddle is the authorized reseller and seller for that transaction, and Ottera supplies and supports Ramosa. The relevant Paddle entity is identified at checkout or in Paddle's Buyer Terms. Paddle handles payment collection, applicable sales taxes, transaction receipts, and payment refunds under its agreement with you. We receive the records necessary to provide access and reconcile the transaction; we do not receive your full card number or card security code.

Paddle's buyer terms govern its sale and payment services. These Terms govern your use of Ramosa. Neither document removes mandatory consumer rights. Our additional refund promise is set out in the Refund Policy; we instruct Paddle to process eligible refunds. We do not describe Paddle as merely our card processor or purport to change its independent contract with you.

10Renewals and price changes

A paid subscription renews automatically for the billing period shown at checkout unless you cancel before renewal. By confirming a recurring purchase, you authorize Paddle to collect the disclosed recurring charge. A free plan does not automatically become a paid subscription. A trial converts to a paid subscription only where the checkout clearly discloses the conversion, timing, price, and cancellation method and you affirmatively accept them.

We or Paddle will provide notices and obtain any further consent required by applicable law. A price increase or material reduction in an ongoing paid plan will not take effect before the end of the current paid period, and we will give at least 30 days' advance notice before the first affected renewal, or longer where required. You may cancel before it takes effect. Where affirmative consent is required, silence is not acceptance.

If a payment fails, Paddle may retry it in accordance with its terms and applicable law. Paid features may become unavailable if payment is not completed, and your account may return to an available free plan. A failed payment does not entitle us to delete your local email files.

11Cancellation and refunds

Cancel renewal using the subscription-management link in your Paddle receipt or the buyer support tools at paddle.net. You may also ask us at [email protected] to arrange cancellation. We will act on a clear, timely request without requiring a telephone call or a reason for leaving.

Ordinary cancellation stops future renewals and leaves paid access available until the end of the paid period. A refund or legal withdrawal may end the refunded access sooner. Our Refund Policy provides a 14-calendar-day no-reason refund promise and explains its transaction coverage, how to request it, and statutory rights that remain available afterward.

Uninstalling the application, removing a mailbox, or clearing local data does not cancel recurring billing. If you request account closure, we will also arrange cancellation of any linked Ramosa renewal and confirm its status. Charges made after the effective cancellation in error will be corrected. Account closure is not a condition of receiving a refund.

12Changes and availability

We may maintain, improve, or update the Service and address security, legal, provider, or compatibility changes. Internet access, provider availability, and supported software are required for online functions. We do not promise uninterrupted availability or a particular AI provider or model. Any provider change must preserve the data-use restrictions we have promised and follow applicable notice and consent requirements.

We will give reasonable notice of a discontinuation or change that materially disadvantages you, unless urgent security or legal circumstances prevent it. If we stop a paid service or materially remove a purchased core function during a paid period and cannot provide an appropriate remedy, you may terminate the affected service and receive a proportionate refund for the unavailable remainder, without limiting greater legal rights. Updates necessary to maintain legally required conformity will be provided as applicable law requires.

13Suspension and termination

You may stop using the Service and request account closure at any time. We may restrict or suspend affected functions where reasonably necessary to address a material breach, nonpayment, unlawful conduct, an actual security risk, or a binding legal requirement. We will use a proportionate response and, where practicable, explain the reason and allow an opportunity to correct a remediable breach. We may act immediately where delay would cause harm or where notice is legally prohibited.

You may challenge a suspension by contacting us. We will review the relevant information. Termination does not automatically forfeit a refund right or permit us to retain payment for service that law requires us to refund. Where lawful and technically feasible, you will have a reasonable opportunity to obtain cloud account information before routine deletion. Local copies remain on your devices until you remove them. Sections intended to operate after termination, including accrued payment and refund rights, confidentiality restrictions, liability, and dispute provisions, continue only as necessary for that purpose.

14Our responsibilities and liability

We will provide the Service with reasonable care and skill and honor applicable warranties, conformity requirements, and remedies. Nothing in these Terms excludes or limits liability for fraud, fraudulent misrepresentation, willful misconduct, gross negligence where exclusion is prohibited, death or personal injury caused by negligence, or any other liability that law does not permit us to exclude or limit. Nothing limits rights or remedies under applicable consumer or data protection law.

Consumers. If you use Ramosa mainly outside your trade or profession, we are responsible for loss that is a foreseeable result of our breach or failure to exercise reasonable care and skill, subject to applicable law. We do not impose the business liability cap below on your mandatory consumer remedies. Reasonable backup precautions may reduce avoidable loss but do not excuse our own legal responsibilities.

Business users. Subject to the non-excludable matters above, neither party is liable to the other for indirect or consequential loss or loss of anticipated profits, business opportunity, or goodwill arising from these Terms. Ottera's total aggregate liability arising from these Terms will not exceed the greater of USD 100 and the amounts paid for your use of Ramosa during the 12 months immediately preceding the event giving rise to the claim. This cap does not limit an obligation to pay an agreed refund or return fees for unprovided service, and does not restrict a data subject's statutory rights. A separate written business agreement may establish different limits.

Except for express commitments and legally required warranties, we do not warrant that every AI output will be correct or that the Service will meet requirements not disclosed or agreed with us. We do not require an individual consumer to indemnify us for every third-party claim arising from use of the Service.

15Governing law and disputes

These Terms and non-contractual obligations arising from them are governed by the laws of the People's Republic of China, excluding its conflict-of-laws rules, subject always to mandatory laws that apply to you. This choice does not deprive a consumer of protections that cannot be waived under the law of the place of habitual residence.

Please contact us first if there is a dispute so we can try to resolve it. This is an invitation, not a condition that delays a statutory remedy or the right to approach a regulator or court. For business users, courts with lawful jurisdiction at Ottera's registered domicile in Shanghai have exclusive jurisdiction, unless mandatory law requires otherwise. Consumers may bring proceedings in any court available under applicable consumer law, including their home courts where those laws provide that right. These Terms do not impose binding arbitration or a class-action waiver.

Paddle's separate agreement determines the law and forum applicable to a dispute about Paddle's own obligations. The choice in these Terms does not rewrite that agreement.

16Changes to these Terms

We may update these Terms for legitimate legal, security, operational, or product reasons. We will identify the effective date and give at least 30 days' notice of a material change that affects an ongoing subscription, except where a shorter period is necessary for law or an urgent security issue. We will explain an urgent change as soon as practicable. Changes do not retroactively remove accrued rights, refunds, or claims.

You may stop using the affected service and cancel renewal before a material change takes effect. Where the law requires renewed agreement, we will obtain it. A policy update does not authorize a new use of Google data or another consent-based activity without the additional consent required for that use.

17General provisions and contact

If a provision is unenforceable, it will be severed only to the extent necessary, and the remaining provisions continue where lawful. A failure to enforce a right is not a waiver. You may not transfer your account or this agreement without our written permission, except where the law gives you that right. We may transfer this agreement in connection with a lawful restructuring or sale only if your protections are preserved; a transfer of Google user data remains subject to the Privacy Policy's explicit-consent requirement.

We may send account, legal, and service notices to your registered email address or through an appropriate in-product notice. Marketing permission is separate. If we provide a translation, the English text is the reference version except where mandatory law requires a local-language text or a more favorable interpretation for a consumer.

Questions, complaints, cancellation requests, and legal notices may be sent to [email protected], or by post to Shanghai Ottera Internet Technology Co., Ltd., Room 581, Building 2, No. 350 Xianxia Road, Changning District, Shanghai, People's Republic of China.
