Terms of Service

Effective date: 10 November 2026
Last updated: 10 November 2026

1. Agreement to These Terms

These Terms of Service (the “Terms”) govern your access to and use of Sissare (the “Service”), operated by PT. Cipta Informatika Solusindo (“we,” “us,” or “our”). By creating an account or using the Service, you agree to these Terms and the Sissare Privacy Policy. If you do not agree, do not create an account or use the Service.

2. What Sissare Does

Sissare is an end-to-end encrypted document storage and sharing service. Documents are encrypted on your device before upload. We store encrypted document objects and the account, public-key, and encrypted-key information needed to provide storage, sharing, access control, and succession features. We do not have the private keys required to decrypt your document content.

3. Eligibility and Your Account

• You must be at least 18 years old to create or use a Sissare account.
• You must provide an email address that you control and use the specific invited email address to accept an email-based invitation.
• One Sissare account may be registered per email address.
• You are responsible for protecting your account credentials, devices, and private keys, and for activity conducted through your account.
• You must keep your account information reasonably accurate and promptly tell us if you suspect unauthorized access.

4. Data Irrecoverability — Read Before Using Sissare

End-to-end encryption is a core security feature, but it also means that lost access may be permanent. This is a fundamental characteristic of the Service, not merely a limitation of customer support.

• We cannot decrypt your documents, reset your document-decryption keys, or recover document content on your behalf. We do not possess the private keys needed to do so.
• If you lose access to your device or private keys and no other authorized collaborator or configured Successor has a usable key copy, the affected documents may become permanently unreadable, including by you.
• A Successor can access a document without the original owner’s device or private key because the Successor already holds their own wrapped copy of that document’s key. The Service does not need to decrypt the document or recover the original owner’s private key to enable this access.
• Removing the last remaining authorized key-holder, revoking all access, or permanently deleting an account may make the affected documents permanently unreadable or cause their encrypted objects to be deleted, depending on the choices made in the Service’s deletion workflow.
• We strongly recommend configuring a Successor for important documents, keeping your devices and private keys secure, and ensuring that another authorized person has access where appropriate.

By using Sissare, you acknowledge that you understand this trade-off. Encryption reduces our ability to access your content, but it also means we cannot rescue content when all usable key copies are lost.

5. Documents, Sharing, and Successors

You retain responsibility for the documents you upload and for deciding who may access them. You must have the rights and permissions necessary to upload, store, and share each document.

Sissare provides collaboration roles and access controls, which may include Owner, Co-owner, Editor, and Viewer roles. The permissions available to each role are described in the Service. You are responsible for reviewing recipients and permissions before sharing sensitive documents.

A Successor is a person you designate to take over a document under the Service’s succession functionality. A Successor can already open the document, and becomes its Owner automatically if you permanently delete your account or if you are inactive for the period set out in the Service. As Owner they take over its ownership and storage use, which may count against their plan, and the previous Owner is kept as a Co-owner except where the account was deleted. A Successor must already hold their own wrapped copy of the document key. This allows the Successor to access the document without the original owner’s device or private key. You are responsible for choosing an appropriate Successor and keeping the designation up to date.

We provide technical tools for sharing, permission changes, revocation, and succession. We are not a party to private disputes between users about document ownership, authorization, or the appropriateness of a Successor, and we do not undertake to mediate those disputes.

6. Account Deletion and Document Disposition

You may request deletion of your account through the Service. A 30-day grace period applies. During this period, your account is deactivated but recoverable, and you may cancel the deletion request and restore your account, subject to the Service’s recovery process.

Before you can request deletion, you must review the documents you own. For each document that has no Successor, you choose whether to leave it for the people who can still open it or delete it for everyone. A document with a Successor transfers to that Successor when the grace period ends.

A document you leave is kept if anyone else can still open it, and it remains recorded against your deleted account’s internal identifier. A document that nobody else can open is deleted, as is any document you chose to delete for everyone. Your own access to documents owned by others is removed. If you do not remove a collaborator’s access before you delete your account, that collaborator keeps the access their own key copy provides.

Deletion of an object from Cloudflare R2 makes it unavailable and unrecoverable through the R2 API. Sissare does not offer a user-visible R2 backup or soft-delete recovery window. We cannot state when Cloudflare physically erases the underlying storage media. Once permanent deletion has occurred, we may be unable to restore deleted objects or access records.

You are responsible for checking the document choices shown in the deletion workflow before confirming permanent deletion. If all usable encrypted key copies are removed or lost, the document may be permanently unreadable even if an encrypted object still exists.

7. Plans, Subscriptions, and Payments

Sissare offers Free, Plus, and Pro plans. The storage, collaborator, file-size, and other limits applicable to each plan are described in the Service or on the Sissare pricing page and may change in accordance with these Terms and applicable law.

• Paid subscriptions are purchased through the app store available on your device (currently Google Play; Apple App Store purchases will be offered when they become available). The applicable store processes payment and provides subscription management, cancellation, and refund mechanisms.
• Prices may vary by country or storefront. The price and billing period displayed to you by the relevant app store at the time of purchase apply to your purchase.
• Subscriptions may renew automatically unless cancelled through the relevant app-store account before the renewal deadline specified by that store. The store’s displayed renewal, cancellation, and refund terms apply to the transaction.
• We do not receive or process your app-store payment-card details. We receive purchase or entitlement information needed to activate and administer your plan.
• Add-on storage purchases, where offered, apply to the account for which they were purchased and are not transferable to another account unless the Service expressly says otherwise.
• Redeem codes, where offered, are subject to their stated conditions, are non-transferable, and may be restricted to the account for which they were issued.
• If a plan change, cancellation, or expiration causes a document you own to exceed the collaborator or other limits of your new plan, the Service may notify you and provide an opportunity to adjust the document’s collaborators or usage before applying the relevant limits. The timing and available options will be described in the Service.

Nothing in these Terms limits any refund, cancellation, or other consumer right that cannot lawfully be limited.

8. Acceptable Use

You agree not to use Sissare to store, share, or distribute content or engage in conduct that:

• infringes another person’s copyright, trademark, privacy, or other legal rights;
• violates applicable law or a binding court or government order;
• threatens, harasses, exploits, or facilitates harm to another person;
• distributes malware or attempts to compromise the Service, another user’s account, or another system; or
• interferes with the security, availability, or normal operation of the Service.

Because document content is end-to-end encrypted, we cannot routinely inspect documents or proactively determine whether their contents violate these rules. We may act on account-level information, abuse signals, user reports, legal notices, or other information available to us. Depending on the circumstances and applicable law, we may investigate, restrict sharing, suspend, or terminate an account. We will not claim to have reviewed document contents that we cannot decrypt.

9. Copyright Complaints

If you believe that material stored or shared through Sissare infringes your copyright or other intellectual-property rights, you may send a notice to support-sissare@ciptais.com with the subject line “Copyright Complaint.” Include:

• your name and contact information;
• identification of the work or right you claim has been infringed;
• the relevant Sissare document, account, or share-link identifier, if known;
• an explanation of the alleged infringement and the basis for your authority to submit the complaint; and
• a statement that the information in your notice is accurate and that you are acting in good faith.

Do not send us the confidential contents of a document unless you are authorized to disclose them. Because we cannot decrypt document content, a description of the content alone may not allow us to identify or verify the material. We may request additional information, preserve relevant account-level information where lawful, restrict access or sharing where technically and legally appropriate, or take other action based on the information available to us.

We will review notices in good faith and respond as appropriate under applicable law. This section describes our complaint channel; it does not represent that we have registered a designated agent with the United States Copyright Office or that we qualify for any particular statutory safe harbor. We have not registered a DMCA agent as of the effective date of these Terms.

10. Third-Party Services

The Service relies on third-party providers, including Oracle Cloud Infrastructure, Cloudflare R2, Google (Firebase Cloud Messaging, for push notifications), Apple App Store, and Google Play. Your use of app-store services is also subject to the relevant provider’s terms. We are not responsible for independent third-party services, but this does not limit our obligations under applicable law for the Service we operate.

11. Disclaimers and Limitation of Liability

We work to provide a reliable and secure Service, but the Service is provided on an “as is” and “as available” basis to the maximum extent permitted by law. We do not promise uninterrupted availability, that every defect will be corrected, or that the Service will meet every individual requirement.

You acknowledge the specific risks described in Section 4. To the extent permitted by applicable law, we are not responsible for a loss of document access that results from your loss of private keys or devices, the absence or loss of another authorized key-holder, your succession or sharing choices, or your confirmation of permanent deletion after the document-disposition workflow. This does not exclude responsibility for our own breach of these Terms, unlawful conduct, negligence where liability cannot lawfully be excluded, or any other liability that applicable law does not permit us to exclude.

To the maximum extent permitted by applicable law, our aggregate liability for claims arising out of or relating to the Service will not exceed the amount you paid for the Service, including through an applicable app store, during the twelve (12) months before the event giving rise to the claim. This limitation does not apply to liability that cannot lawfully be limited, including any mandatory consumer rights or remedies.

Nothing in these Terms excludes or restricts rights or remedies you have under mandatory consumer-protection or other applicable law.

12. Suspension and Termination

You may stop using the Service and request account deletion as described in Section 6. We may suspend or terminate access if we reasonably believe you have materially violated these Terms, created a security risk, used the Service unlawfully, or if we are required to do so by law. Where reasonably practicable and lawful, we will provide notice and an opportunity to address the issue.

Suspension or termination does not restore or recover document keys. The data-irrecoverability and document-disposition provisions in Sections 4 and 6 continue to apply.

13. Changes to the Service or These Terms

We may modify the Service or these Terms to reflect product changes, security requirements, or changes in law. We will provide notice of material changes through the Service or by email before they take effect where required by law. The revised Terms will state their effective date. If you do not agree to a material change, you should stop using the Service and may request account deletion, subject to Section 6 and applicable law.

14. Governing Law and Disputes

These Terms are governed by the laws of the Republic of Indonesia, without prejudice to mandatory legal protections that apply to consumers in their place of residence.

We encourage you to contact us first at support-sissare@ciptais.com so we can try to resolve a dispute informally. If a dispute cannot be resolved informally, it will be submitted to the competent courts having jurisdiction in South Tangerang, Banten, Indonesia, subject to any mandatory dispute-resolution rights or procedures under applicable law.

15. General

If any provision of these Terms is held unenforceable, the remaining provisions will continue to apply to the extent permitted by law. Our failure to enforce a provision is not a waiver of our right to do so later. You may not transfer your rights or obligations under these Terms without our prior written consent, except where applicable law provides otherwise. These Terms and the Privacy Policy form the agreement between you and us concerning your use of the Service.
