Terms of Service

Article 1 (Application)

These Terms of Service (the "Terms") set out the conditions on which Endots (sole proprietor), operated by Koryu Kawatani ("we", "us" or "our"), provides the service known as "SoleKado" (the "Service"). By using the Service, the User accepts the Terms.

Matters not covered by the Terms are governed by the individual notices displayed on the Service. A notice shown on a screen does not, however, alter what the Terms provide; the Terms may be amended only by the procedure set out in Article 13.

Article 2 (Definitions)

In the Terms, the following words have the meanings given below.

the Service

The web application that we provide under the name "SoleKado", which supports the recording of contracts and hours worked and the preparation of documents, together with the website related to it.

the App

The program part of the Service, which runs in the User's browser.

the User

An individual or a corporation that accepts the Terms and uses the Service.

User Data

Information entered into the App by the User, or generated by the App, and stored on the User's device. It includes contracts, work logs, business details and the documents produced.

the Paid Plan

The paid form of use (Pro) described in Article 5, including where it is provided free of charge or at a discount under that Article.

the Licence

The information issued under our signature that evidences an entitlement to the Paid Plan.

Article 3 (How the Service is provided)

The Service runs in the User's browser. Both the information entered into the App by the User and the documents produced by the App are stored only in the browser storage area (IndexedDB) on the User's device. None of it is transmitted to our servers, and we can neither obtain nor read any of it. Where the User has subscribed to the Paid Plan or has a Licence registered in the App, however, the App transmits to our servers the identifier of the checkout session when the Licence is collected, and the Licence itself when checking whether it has been renewed or when opening the portal for changing the payment method or cancelling. How this is handled is set out in the Privacy Policy.

Use of the Service requires an internet connection and a supported browser. Communication charges and the provision of a device are borne by the User.

• Invoices, timesheets (稼働明細), expense reports (経費明細), work reports (業務報告書), quotations (見積書) and other documents are produced entirely on the device.
• Contract PDFs, and the text read from receipt images, are both handled on the device alone. The files and training data used to read them are fetched from this site, and neither the images nor the text read from them is sent to an external API or to generative AI.
• The Google Calendar integration operates on authorisations the User grants through one or more Google accounts the User chooses, each authorised separately. Importing events uses two permissions and no more: reading events, and reading the list of calendars. Imported events, and the email addresses of the connected accounts, are stored on the device, and we do not receive them.
• Only where the User uses the feature that writes hours worked out to a calendar do we request a third permission, for the one Google account chosen as the export destination only, and we request it the first time that feature is used (incremental authorisation). That permission reaches nothing but the dedicated calendar the App itself creates (named "SoleKado 稼働"), within which it creates, updates and deletes events. Events that the User already holds can be neither read nor changed nor deleted with it. Where the export feature is not used, the permission is never requested.
• The integration can be disconnected at any time, one Google account at a time. On disconnection, if the App can obtain a valid access token for that account, we also ask Google to revoke the authorisation and show whether it was revoked. Because the App never stores access tokens, where no such token can be obtained or the revocation fails, disconnecting only removes the connection on the device. In that case, please also revoke access from the settings of the Google account, at https://myaccount.google.com/permissions

Article 4 (Accounts)

The Service requires no account registration. We issue no ID or password to the User. Of a person who merely uses the App we hold no information at all, including name and contact details, and we have no means of knowing who is using it. During the limited beta, however, we hold the email addresses of those who may open the screens of the App (section 1 of the Privacy Policy).

Only where a User subscribes to the Paid Plan (including subscribing with a code that makes it free of charge) do we receive, from Link (a service provided by affiliates of Stripe that handles the checkout and the collection of payment on our behalf, the sale itself being handled by Sold through Link, LLC; "Link"), the purchaser details it shares with us, including an email address; we also keep a record of the issuance of the Licence. The purposes for which these are used, and how they are handled, are set out in the Privacy Policy.

In either case, we cannot offer any procedure that presupposes an account, such as reissuing a password or transferring or recovering data on our side. When changing device or browser, please take a backup as described in Article 6.

The Paid Plan takes effect when the Licence issued on purchase is registered in the App. Because the Licence is not tied to any account, the User is responsible for keeping and managing it.

Article 5 (Fees and payment)

The Service has a range that may be used free of charge (Free) and a Paid Plan (Pro). The features that produce documents are intended to belong to the Paid Plan, while the features for recording are intended to remain available free of charge.

We have not yet begun selling the Paid Plan to the general public. At present every feature, the production of documents included, may be used free of charge. We will give notice on the Service in advance of when general sales of the Paid Plan begin, and of when the features that produce documents become part of the Paid Plan and what will remain free of charge from then on.

The amount of the fees and the methods of payment are those displayed on the Service and on the purchase screen, and those stated in the Notice under the Act on Specified Commercial Transactions (特定商取引法). We may provide the Paid Plan free of charge or at a discount, on terms that we have set out to the User individually. In that case too, the provisions of this Article concerning payment, renewal and cancellation apply.

• The checkout and the collection of payment for the Paid Plan are handled by Link on our behalf, and a payment made to Link settles the fee for the Paid Plan. The User's full card number and security code never reach us.
• The Paid Plan renews automatically on the expiry date of the current term. A User who does not wish to renew must cancel no later than the day before the next renewal date.
• After cancellation, the features of the Paid Plan remain available until the last day of the period already paid for, and no charge is made from the next renewal date onwards.
• Where the User cancels of their own accord, fees corresponding to a period already provided are not refunded, including on a pro rata basis. This does not apply where the Service was unavailable for reasons attributable to us, or where a refund is required by law. Refunds where we discontinue the Paid Plan are governed by Article 12. Link may also make a refund under its own refund policy.
• If we change our fees, we will give notice on the Service at least 30 days before the renewal date on which the new fees take effect.

We have not yet begun selling the Paid Plan to the general public. Every feature, the production of documents included, may currently be used free of charge. We will give notice on the Service of when general sales begin.

Article 6 (User Data and the User's responsibility)

User Data exists only on the User's device. We hold no copy of User Data, and therefore cannot restore User Data that has been lost. Taking and keeping backups is the responsibility of the User.

User Data can be exported as a JSON file from the settings screen of the App. That file contains business details (including bank account numbers) and client names in unencrypted form. Please take care where it is kept.

The App saves the data as of the first time the App is opened each day, and the data from right before a restore from a backup or an action that changes many records at once (deleting a contract, deleting or importing work logs in bulk, and so on), as snapshots on the same device (on-device snapshots). The snapshots are on the User's device and are lost together with User Data in the circumstances below. A file exported from a snapshot contains the same information as the file described in the preceding paragraph, in unencrypted form. Having snapshots does not remove the need to take and keep backups.

User Data is lost in the circumstances below. We can detect none of them, and we cannot restore the data in any of them.

• Failure, loss or reset of the device
• Clearing the browser's history or site data, or reinstalling the browser
• Use in a private (incognito) window, where the data is discarded as soon as the window is closed
• Automatic eviction of storage by the browser, for example after a long period without access
• Use on another device or in another browser; User Data is not shared across devices or browsers

Article 7 (Prohibited conduct)

The following conduct is prohibited in connection with the Service.

• Conduct that violates laws or regulations or public order and morals
• Conduct that infringes the intellectual property rights or other rights of us or of a third party
• Circumventing the verification of the Licence, or modifying the App
• Transferring, lending, sharing or publishing the Licence to or with a third party
• Copying the Service and redistributing or reselling it to a third party
• Reverse engineering the App, except where it is permitted by law
• Placing an excessive load on the servers we use to issue Licences or to deliver the Service
• Producing documents whose contents are untrue, for the purpose of deceiving a third party
• Any conduct comparable to the above

Article 8 (Intellectual property)

Copyright and other intellectual property rights in the Service and the App belong to us or to the third parties that properly hold them. The Terms grant a non-exclusive right to use the Service; they do not transfer any of those rights to the User.

Rights in the information entered into the App by the User (other than the Licence), and in the documents produced by the App, belong to the User or to the person properly holding them. We neither acquire nor use them. They never reach us in the first place.

Where the User registers in the App a form received from a client (an Excel file, for example), it is for the User to confirm that doing so does not conflict with the User's contract with that client. The App cannot write values into cells of a form that hold a formula, or into any cell of a merged range other than its top-left cell; and a form that the App, on inspecting it at registration, judges it cannot handle cannot be registered.

Article 9 (No tax, legal or accounting advice)

The Service is a tool that records contracts and hours worked and assists in assembling documents from those records. It does not make judgements of law or practice on the User's behalf.

We do not warrant that the invoices, timesheets, expense reports, work reports, quotations or other documents produced by the App conform to the contract between the User and the client, or to the laws and practice that apply. Checking their contents and deciding whether to submit them — including tax rates, rounding, whether a given item must be stated, and the treatment of Japan's consumption tax (消費税) — rests with the User.

The totals and amounts shown by the App are derived from what the User has entered. If the input is wrong, the result is wrong.

We do not warrant the completeness or accuracy of the information and other material that the User obtains through the Service (including the contents of the documents the App produces and the results of its calculation of amounts), and we are not liable for damage arising from its being inaccurate or incomplete, except where the damage is caused by our wilful misconduct or gross negligence.

To help draft work reports and other documents, the App may prepare text for the User to give to a generative AI that the User chooses and uses of their own accord. The answers of that generative AI come from the third-party service that provides it, not from us. We do not warrant the completeness or accuracy of what the User takes into the App from those answers; checking and correcting it, and deciding whether to submit it, rest with the User. Choosing what information to give to the generative AI, and checking that generative AI's terms of use, also rest with the User. We are not liable for damage arising from those answers being inaccurate or incomplete, except where the damage is caused by our wilful misconduct or gross negligence.

The Service does not provide advice on tax, legal or accounting matters. For a final judgement on whether a document is correct, please consult a qualified professional such as a tax accountant or a lawyer.

Article 10 (The Electronic Books Preservation Act)

The Service satisfies none of the storage requirements laid down by the Electronic Books Preservation Act (電子帳簿保存法): it applies no timestamp, it keeps no history of corrections and deletions, and it meets none of the search requirements.

Records kept in the App, and files exported from the App, therefore cannot be treated as storage under that Act. Books and documents relating to national taxes must be stored separately, by a method that does meet the requirements.

The Service does not meet the storage requirements of the Electronic Books Preservation Act (電子帳簿保存法). Any storage required by law must be carried out separately by the User.

Article 11 (Limitation of liability)

We do not warrant that the Service is fit for any particular purpose of the User, or that it will be provided without interruption or defect.

We are not liable for damage suffered by the User through use of the Service, except where the damage is caused by our wilful misconduct or gross negligence.

Where the User uses the Service free of charge (including where the User uses the Paid Plan free of charge), we are not liable for damage suffered by the User through use of the Service, except where the damage is caused by our wilful misconduct or gross negligence.

Where the User uses the Paid Plan for a fee and we are liable to compensate for damage (other than in cases of our wilful misconduct or gross negligence), that liability extends only to direct and ordinary damage, and does not include lost profits or any other indirect damage. The amount is capped at a sum equal to one month's fee for the Paid Plan that the User is using at the time the damage arises (for an annual plan, one twelfth of the annual fee).

Where the User is a consumer within the meaning of the Consumer Contract Act (消費者契約法), the provisions of the Terms that exempt us from, or limit, our liability to compensate for damage do not apply, and we bear liability in accordance with the law.

Any dispute arising between the User and a client or another third party is to be resolved by the User, at the User's own responsibility and expense. Nor are we liable for defects arising from the device, the browser or the network, or from a failure or a change of specification in a service provided by a third party such as Google Calendar or a business that handles payment, to the extent that they are not attributable to us.

Article 12 (Change, suspension and discontinuation of the Service)

We may change what the Service contains, or discontinue providing it. Where we discontinue it, we will give notice on the Service a reasonable period in advance.

We may suspend the Service temporarily in order to carry out maintenance or to deal with a failure. Except in an emergency, we will give notice in advance.

Where we discontinue the Paid Plan of our own accord, we will refund the fees corresponding to the unexpired part of the term, calculated pro rata. We will write to the email address that Link shared with us (Article 4), and will make the refund through Link, as a rule by the method used for payment (where the shared details have been deleted, notice is given by posting on the Service and in reply to enquiries). Where the User cancels of their own accord, no pro rata refund is made, as set out in Article 5.

Discontinuation of the Service does not of itself erase User Data stored on the User's device. Once delivery of the App has stopped, however, the App can no longer be opened. Where notice of discontinuation is given, please export a backup and produce any documents needed within that period.

Article 13 (Amendment of the Terms)

We may amend the Terms. An amendment is made by one of the two procedures below, and takes effect at the time stated for that procedure.

A User who does not accept an amendment should cease using the Service before the amendment takes effect. The Paid Plan may be cancelled in accordance with Article 5.

• A minor amendment — correcting an error, clarifying wording, or otherwise not substantively altering the rights and obligations of the User — applies from the time the amended Terms are posted on the Service.
• An amendment that restricts the rights of the User or imposes a new obligation on the User takes effect on an effective date that we set, and applies from that date, provided that we give notice of its contents and of that date on the Service at least 30 days beforehand.

Article 14 (Governing law and jurisdiction)

The Terms and the use of the Service are governed by the laws of Japan.

Any dispute arising between us and the User in relation to the Service shall be subject to the exclusive jurisdiction, in the first instance, of the district court having jurisdiction over the location of our place of business.

Article 15 (How to reach us)

Enquiries about the Service should be sent to the contact details given in the Notice under the Act on Specified Commercial Transactions (特定商取引法), at founder@endots.dev.

As a rule, we give notice to Users by posting on the Service. For a User of the free range (other than one who has subscribed to the Paid Plan) we hold no contact details that we could use to write to them, as stated in Article 4 (the email addresses on the limited-beta allow list are held only for access control, that is, to decide whether access is permitted and to send the one-time passcode used to sign in, and we do not use them to write to anyone ourselves), and so have no means of writing to them individually. Please look at the screens of the Service from time to time, so that an important notice is not missed.

A User who has subscribed to the Paid Plan (including with a code that makes it free of charge) may be written to individually, at the email address that Link shared with us (Article 4). Notice of a refund under Article 12 is given in the same way.

Article 16 (Severability)

Even if any provision of the Terms, or any part of one, is held invalid or unenforceable under law or otherwise, the remaining provisions of the Terms, and the remainder of that provision, continue in full force and effect.
