License Agreement.

This agreement is between you and DOSAYGO, a Wyoming corporation, 9450 SW Gemini Dr #44162, Beaverton, OR 97008-7105, USA ("DOSAYGO", "we") and covers Tree Player and Tree Grower (the "Software"). You accept it by ticking the acceptance box when you subscribe, and by installing, activating, or using the Software; we record the version you accepted at purchase. If you use the Software for an organization, you confirm you may bind it. If you do not accept this agreement, do not use the Software.

1. License grant

The Software is licensed, not sold. Subject to this agreement, DOSAYGO grants you a non-exclusive, non-transferable license to use:

  • Tree Player, free of charge, to open and replay Tree Document Format (.tdf) files;
  • Tree Grower, with a paid subscription, to capture and curate .tdf collections on up to three activated devices (section 3).

You may use the Software for personal or commercial work, including making collections for your clients, and your employees and contractors may operate your activations for you. DOSAYGO and its licensors keep all rights not expressly granted.

2. Grower subscription

Renewal. Tree Grower is a subscription billed every two years. It renews automatically at the end of each two-year period and is charged to your payment method until you cancel. If the price changes, we will email you at least 30 days before the renewal it affects.

Cancellation. You can cancel at any time at trees.dosaygo.com/billing (sign in with your purchase email) or from the billing link in your license email. Cancelling stops future renewals; your subscription stays active until the end of the period you have paid for.

Updates. While your subscription is active you may install every Grower update we release. Grower checks with our license service before installing an update and may refuse a version released after your subscription period.

Keeping your version. When your subscription ends, you may keep using, without time limit, every version of Grower released while your subscription was active (your "eligible versions"), subject to this agreement. This continuing license covers the software you have; it does not include updates, hosting, support, or compatibility with future operating systems or browsers. Versions released after your subscription ended require a new subscription. Resubscribing starts a new two-year period from that day; the time you were not subscribed is not billed.

3. Activations and reinstalling

An activation is one installation of Grower on one device you own or control. A license has up to three activations at a time. Copying an activation to another device is not permitted.

To move Grower to another device, choose Help › Deactivate this computer in Grower 2.0.4 or later (or run tree-grower license deactivate). This frees the activation. You can deactivate yourself up to three times in any twelve months. With an earlier version, when you have used those three, or when a device is lost or no longer works, email us: after reasonable checks that you hold the license and are not sharing it, we will free an activation. We do not promise a response time.

After your subscription ends you may still reinstall, activate, and deactivate your eligible versions. We currently keep past releases available for download but do not promise to do so; keep a copy of the installers you rely on.

Tree Player needs no license or activation, and nothing in sections 4 or 7 affects it.

4. License service

Grower renews its license with our license service automatically when it is online, at least every 60 days. If it cannot reach the service for 60 days, it asks you to connect once before it runs again; your version and your collections are unchanged. We do not guarantee that the license service is always available.

If we retire the license service. Before we stop operating it, we will give at least 90 days' notice by email and on trees.dosaygo.com, and do both of the following:

  • each Grower that connects during the notice period receives a license that no longer needs renewal, so the installation keeps working without the service;
  • we publish a final version of Grower that runs without the license service. Everyone who holds a Grower license that has not been revoked may download it, and install and reinstall it on up to three devices at a time, including new or replacement devices and whether or not they connected during the notice period.

This does not oblige us to provide updates after that final version, hosting of the download beyond a reasonable period, support, source code, or maintenance.

5. Restrictions

Except as applicable law permits despite this section, you may not, and may not permit, assist, or direct anyone else (including an artificial-intelligence system, language model, agent, or other automated tool) to:

  • reverse engineer, decompile, disassemble, or otherwise attempt to derive the source code, algorithms, or license mechanisms of the Software, including by supplying the Software or its binaries to an AI system for that purpose;
  • circumvent, disable, or interfere with licensing, activation, device limits, update checks, or other protection measures;
  • use the Software, its binaries, or its outputs to train, build, or improve tools intended to replicate the Software or circumvent its protections;
  • share, transfer, resell, sublicense, or rent the Software, a Grower license, or an activation token, or let anyone other than you, your employees, and your contractors operate your activations;
  • use the Software to break the law, bypass access controls, distribute content unlawfully, or violate the rights of others.

6. Your data and privacy

Your collections are yours. Captures are made and kept on your devices. We do not claim ownership of the collections you create, and you are responsible for the content you capture, keep, and share.

What we never receive. The Software does not send us your browsing, the pages you capture, your .tdf collections, or their contents. What you choose to share, sync, or upload elsewhere is between you and that service.

What the Software does send. Only these requests, for licensing, updates, fraud prevention, and license enforcement:

  • when you activate, deactivate, check whether an update is included, or renew (at least every 60 days while online), Grower sends our license service its license token, the product identifier, its version number, and, when activating or deactivating, the public key of a key pair generated on your device, a device identifier derived from it, and a one-time challenge from the service signed with that key. The service keeps, for each activation, the device identifier and public key, when it was activated, and the time and network address of its most recent renewal, to detect copied activations;
  • both applications ask our release location (trees.dosaygo.com, with GitHub as a fallback) for new versions and download updates from it;
  • the Software may query a public time server to check the device clock.

We will not add any other reporting without first updating this agreement and our privacy notice. Our privacy notice explains how we keep license and billing information and which service providers we use.

7. Suspension and termination

Immediate suspension. We may suspend a Grower license or activation immediately if we reasonably suspect fraud, payment fraud, copied activations, shared or resold tokens, circumvention of section 5, a material security risk, or illegal activity, or where the law requires it.

Termination. We may terminate your license for a material or repeated breach of this agreement. Where a breach can reasonably be fixed, we will first email you and give you 14 days to fix it.

Payments. While a payment dispute is open we may suspend the license that payment bought. We restore it if the payment is kept or restored, or we receive a replacement payment, unless another reason for suspension remains. A payment that is refunded or reversed for good ends only what it paid for: the license it bought, or for a renewal, the updates for that renewal period. Earlier undisputed periods are unaffected unless there is evidence of broader abuse.

How remote disabling works. Our license service stops renewing the license, so Grower stops when it next renews, no later than 60 days after it last renewed. Nothing on your device is deleted, and Tree Player keeps working. If you believe a suspension is mistaken, email us; if it was, we restore your license.

Suspension or termination under this section is the only exception to your right to keep using eligible versions under section 2. On termination you must stop using, and delete, Grower.

8. Refunds

You may request a refund of a Grower payment within three days of activating the license it bought, or, for a renewal, within three days of the renewal charge, by emailing support@dosaygo.com with your receipt. After that, payments are not refundable. A refunded first payment ends the license it bought; a refunded renewal takes back the updates for that period (section 7). A full refund also cancels your subscription, so nothing further is charged. Your rights to cancel a purchase of digital content under consumer law depend on where you live; where they apply, checkout asks for your consent to immediate delivery. Nothing here limits consumer rights that cannot legally be waived.

9. Support

The Software is provided without technical support, uptime commitments, or promises of fixes or features. We help with billing: subscriptions, payments, receipts, refunds within the refund window, and activation errors. Community forums, videos, or other materials we may publish are educational only; they are not support and create no obligation.

10. No warranty

The Software is provided "as is" and "as available", without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, non-infringement, accuracy, or that it will be uninterrupted or error-free. Web capture is imperfect: we do not guarantee complete reproduction, permanent compatibility, legal admissibility, or preservation of any content. Keep independent backups of anything important.

11. Limitation of liability

To the maximum extent permitted by law, DOSAYGO is not liable for any indirect, incidental, special, consequential, or punitive damages, or for loss of data, content, profits, revenue, or use, or business interruption, arising from or related to the Software or this agreement, including losses caused by the end of updates, or by a suspension or termination made in accordance with section 7.

To the maximum extent permitted by law, DOSAYGO's total liability for all claims connected with the Software, taken together and under any legal theory, is limited to the greater of USD 100 and the fees you paid DOSAYGO for Tree Grower in the 24 months before the event giving rise to the first claim.

Nothing in this agreement excludes or limits liability that the law does not allow to be excluded or limited, such as liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, for gross negligence or intentional misconduct where the law requires, or under mandatory consumer or data-protection law.

12. Consumers

Whether you are a consumer is decided by the law that applies to you; entering a company name at checkout does not by itself make you a business. If you are a consumer, you have legal rights that this agreement cannot exclude or limit, including rights about digital content that is faulty or not as described. Nothing in this agreement affects them.

13. Governing law

This agreement is governed by the laws of the State of Wyoming, USA, without regard to conflict-of-law rules. The state and federal courts located in Wyoming have exclusive jurisdiction, except where the law of your residence gives you a right to bring proceedings elsewhere. Either party may ask a court for an injunction to stop a breach of section 5, subject to that court's requirements.

14. General

Changes. We may update this agreement and will post each version here. We will email subscribers about material changes at least 30 days before they apply; a material change applies to your subscription from your next renewal, and you can cancel before then. Changes required by law, or needed to address fraud or security, may apply sooner. No change reduces your right to keep using eligible versions under section 2.

Order of precedence. If documents conflict, the first in this list governs: a written agreement signed by DOSAYGO; the price, billing term, and activation count shown at checkout; this agreement; our terms of use. Our privacy notice describes how we handle personal information. Other descriptions of the Software, such as marketing copy, do not change this agreement. Together these are the entire agreement about the Software.

Other terms. You may not transfer this agreement without our consent; we may transfer it as part of a merger, acquisition, reorganization, or sale of assets. If any part is unenforceable, it is limited to the minimum extent needed and the rest remains in effect. Payment obligations already due, and sections 5, 6, and 10 to 14, survive termination. We send notices to the email address on your license.
