Terms of Service

Product: ExcelRewind · Effective date: 2026-08-04

These Terms of Service (the "Terms") are a binding agreement between you and Aptbyte Ventures ("we", "us", "our"), the operator of ExcelRewind (the "Service"). The Service includes the Excel add-in, the Google Sheets add-on, the optional desktop companion application, the web viewer, the account and team consoles, and the websites at excelrewind.com. By creating an account or using the Service, you agree to these Terms and to our Privacy Policy. The installable software is additionally licensed under our End-User Licence Agreement (EULA); if the EULA and these Terms conflict about the software licence itself, the EULA controls.

1. Acceptance and eligibility

• You must be at least 18 years old, or the age of majority where you live, to create an account. If you are younger, you may use the Service only through an educational or other organization that has accepted these Terms and obtained any consent required by law.
• If you use the Service on behalf of a company, school, or other organization, you represent that you have authority to bind that organization, and "you" includes it.
• If you do not agree to these Terms, do not use the Service.

2. What the Service is

ExcelRewind records a spreadsheet editing session — cell edits, text notes, optional microphone audio and webcam video, and an optional workbook snapshot — into a separate, shareable, replayable session file (.rewind). The session file can be replayed in the web viewer without any installation, or inside the add-in.

• The Service never modifies your original spreadsheet. The .rewind file is a companion file saved alongside your workbook.
• Recording is local. Session files are built and saved on your device. They are transmitted to us only in the two cases described in the Privacy Policy: a Kiosk/Exam-mode submission (uploaded for review by the organization that set the exam) and attachments you individually opt in to when sending a bug report.
• Feature availability varies by subscription tier, as described on our pricing page. We may add, change, or remove features; we will not materially reduce the core functionality of a paid tier during a period you have already paid for without notice and the remedies in Section 4.

3. Accounts and security

• You sign in with your email address (one-time code) or Google sign-in. You are responsible for maintaining control of your email account and any device signed in to the Service, and for all activity under your account.
• Keep your account information accurate. Notify us at [email protected] promptly if you suspect unauthorized use of your account.
• We may limit the number of devices concurrently signed in to one account.
• One person per account. Accounts may not be shared, sold, or transferred, except that Team/Enterprise seats may be reassigned by the organization's administrator.

4. Subscriptions, billing, and auto-renewal

4.1 Plans and payment

• The Service offers a free tier and paid subscription tiers (currently Starter, Team, and Enterprise) as described on the pricing page. Team and Enterprise plans are sold per seat.
• Payments are processed by Stripe through Stripe-hosted checkout. Your purchase is made directly with us via Stripe; it is not transacted through, billed by, or refundable through Microsoft, Google, or their marketplaces. Stripe's own terms and privacy policy apply to the payment itself.
• Prices are stated at checkout and are exclusive of taxes unless stated otherwise; you are responsible for any applicable taxes, levies, or duties.

4.2 Auto-renewal and cancellation

• Subscriptions renew automatically at the end of each billing period until cancelled. By subscribing you authorize recurring charges to your payment method.
• You can cancel at any time from your account console at account.excelrewind.com or by emailing [email protected]. Cancellation takes effect at the end of the current billing period; you keep paid features until then.
• If a renewal payment fails, we may retry it and notify you; if it continues to fail, your account may be downgraded to the free tier.

4.3 Price changes

We may change subscription prices. We will give you at least 30 days' notice (by email or in-product) before a price change affects you, and the new price applies only from your next renewal. If you do not agree, cancel before the renewal takes effect.

4.4 Refunds

If you are unhappy with a first purchase of a paid subscription, contact [email protected] within [OWNER — confirm refund window; suggested: 14 days] of that first charge for a full refund. Renewal charges and later billing periods are otherwise non-refundable, and cancellations do not entitle you to a pro-rata refund of the current period. Nothing in this section limits any non-waivable statutory refund or withdrawal rights you have under the consumer law of your jurisdiction.

5. Licence to use the Service; licence enforcement

• Subject to these Terms and payment of any applicable fees, we grant you a limited, non-exclusive, non-transferable, revocable licence to use the Service for your tier and seat count. The installable software is licensed under the EULA.
• Your subscription and licence status are validated against your account. The add-in checks this status periodically and tolerates short offline periods; extended offline use may temporarily limit signed-in features.
• We may suspend or disable a licence — for an individual account or, where necessary, Service-wide — for material breach of these Terms, non-payment, suspected fraud or abuse, security incidents, or where required by law. Where practicable we will notify you and give you an opportunity to remedy the issue.
• Suspension or termination does not take away your local files: .rewind files already saved on your device remain yours and remain playable in the web viewer.

6. Your content and ownership

• Your content stays yours. Your spreadsheets, workbooks, cell data, recordings, notes, audio, video, and .rewind session files are and remain your property (or that of your licensors). We claim no ownership of any of it.
• We hold almost none of it. By design, recording is local and your spreadsheet content is not sent to us. Content reaches our systems only as a Kiosk/Exam-mode submission or as an opt-in bug-report attachment (see the Privacy Policy).
• Limited licence to us. Solely for content that does reach our systems, you grant us a non-exclusive, worldwide, royalty-free licence to host, store, transmit, and display that content only as needed to operate the Service — that is, to deliver an exam submission to the organization that set the exam, or to investigate the bug you reported. This licence ends when the content is deleted from our systems.
• No secondary use. We do not process, analyse, or access the content of your session files for any purpose other than delivering the Service, and we never use your spreadsheet or session content for advertising or to train machine-learning models.
• Encryption and passphrases. Where session-file encryption is enabled for your account, encryption keys and passphrases are controlled by you (or your organization). We cannot decrypt, recover, or reset them. If a passphrase is lost, the encrypted file cannot be opened — by you or by us.
• Recording other people. If your recordings capture other people (for example their voice on microphone audio or their image on webcam video), you are responsible for obtaining any consents required by applicable law before recording or sharing.
• Not a backup service. Session files live on your device (or wherever you choose to store them). You are responsible for backing up your spreadsheets and your .rewind files.

7. Organizational use (Team, Enterprise, exams)

• If your account is provisioned or managed by an organization (a Team or Enterprise plan, a sponsored cohort, or an exam), that organization's administrator can manage your membership, seat, licence status, and certain settings — including, as described in the Privacy Policy, usage-analytics collection for members.
• Kiosk/Exam-mode submissions are delivered to the organization that set the exam. That organization is the party responsible for how it uses submissions and for obtaining any consents required from participants.
• The organization is responsible for its members' compliance with these Terms.

8. Acceptable use

You agree not to, and not to help anyone else to:

• use the Service in violation of law, or to record, store, or share content you have no right to record, store, or share;
• circumvent, disable, or interfere with licence enforcement, tier or seat limits, encryption, or exam-integrity features (including tampering with Kiosk/Exam mode or a submission);
• probe, disrupt, or overload the Service, or access accounts, systems, or data without authorization;
• upload malware or use the bug-report or submission endpoints for anything other than their purpose;
• resell, sublicense, rent, or provide the Service to third parties as a service bureau, except as an organization administering its own seats;
• reverse engineer, decompile, or disassemble the software except to the extent the EULA or applicable law expressly permits; or
• misrepresent your affiliation with us, or use our name or marks except as allowed by Section 9.

9. Intellectual property

• The Service — including the software, websites, design, documentation, and the ExcelRewind name and logo — is owned by us or our licensors and is protected by intellectual-property laws. Except for the licences expressly granted to you, we reserve all rights.
• The .rewind container format does not give us any rights over the content you store in it (see Section 6).
• If you send us feedback or suggestions, you grant us a perpetual, irrevocable, royalty-free licence to use them without obligation to you.

10. Third-party services and platforms

• The Service runs on and alongside third-party platforms — Microsoft Excel and Office, and Google Sheets and Google Workspace — which are governed by their own terms. We are an independent product and are not affiliated with, endorsed by, or sponsored by Microsoft or Google, and we are not responsible for their platforms, marketplaces, or changes they make that affect the Service.
• Payments are processed by Stripe; authentication, data storage, and content delivery use infrastructure providers listed in the Privacy Policy.
• Your use of any third-party service is at your own risk and subject to that third party's terms.

11. Disclaimers

THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE". TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE DISCLAIM ALL WARRANTIES, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, AND NON-INFRINGEMENT. WITHOUT LIMITING THE FOREGOING:

• session capture depends on events reported by the host platform (Excel or Google Sheets); timing is approximate and we do not warrant that every intermediate change, state, or input will be captured;
• we do not warrant that the Service will be uninterrupted, error-free, or secure, or that defects will be corrected; and
• the Service is not a backup, audit, compliance, or record-retention system, and no output of the Service constitutes professional advice.

Some jurisdictions do not allow certain warranty exclusions; where that is the case, the exclusions apply to the fullest extent permitted, and consumers retain their non-waivable statutory rights.

12. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW: (a) NEITHER PARTY IS LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, REVENUE, DATA, OR GOODWILL, EVEN IF ADVISED OF THE POSSIBILITY; AND (b) OUR TOTAL AGGREGATE LIABILITY ARISING OUT OF OR RELATING TO THE SERVICE OR THESE TERMS IS LIMITED TO THE GREATER OF (i) THE AMOUNTS YOU PAID US FOR THE SERVICE IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM AND (ii) [PLACEHOLDER — fixed liability floor, e.g. US$100; counsel to confirm amount and enforceability].

These limits do not apply to liability that cannot be limited by law, including (where applicable) liability for death or personal injury caused by negligence, fraud, or wilful misconduct, or to your payment obligations.

13. Indemnity

If you use the Service in the course of a business or on behalf of an organization, you will defend and indemnify us against third-party claims, and resulting damages and reasonable costs, arising from (a) your content or recordings (including missing consents under Section 6), (b) your breach of these Terms, or (c) your violation of law — except to the extent caused by us. We will notify you promptly of any such claim and reasonably cooperate at your expense.

14. Suspension and termination

• You may stop using the Service and delete your account at any time (see the Privacy Policy for data deletion).
• We may suspend or terminate your access as described in Section 5, or on notice if we discontinue the Service; if we discontinue a paid Service you have prepaid for, we will refund the unused portion.
• On termination, Sections 6 (ownership), 9, 11, 12, 13, 16, and 17 survive. Your local .rewind files remain yours and remain playable in the web viewer.

15. Changes to these Terms

We may update these Terms. The effective date above will change, and for material changes we will give you advance notice in-product or by email. Changes apply from their effective date; your continued use of the Service after that date is acceptance. If you do not agree, stop using the Service and, if you have a subscription, cancel it before your next renewal.

16. Governing law and dispute resolution

These Terms, and any dispute arising out of or relating to them or the Service, are governed by the laws of India, without regard to conflict-of-laws rules. Subject to the mandatory-rights carve-out below, the courts at Delhi, India shall have exclusive jurisdiction. [Counsel to confirm before relying on this: whether to add binding arbitration seated in Delhi under the Arbitration and Conciliation Act, 1996 (with a class-action waiver and carve-outs for small-claims and injunctive relief), and any consumer-law override language for EU/UK and Indian consumers.]

Regardless of the choices above, consumers in jurisdictions whose law grants them mandatory protections, or the right to sue in their local courts, keep those rights.

17. General

• These Terms, the EULA, and the Privacy Policy are the entire agreement between you and us about the Service and supersede prior agreements on that subject.
• If any provision is found unenforceable, the rest remains in effect.
• You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets, with notice to you.
• Our failure to enforce a provision is not a waiver of it.
• You are responsible for complying with export-control and sanctions laws applicable to your use of the Service.
• Neither party is liable for delay or failure caused by events beyond its reasonable control.
