Terms of Service

Last updated: July 7, 2026

These Terms of Service ("Terms") govern your access to and use of Columnam (the "Service"), including the iOS application and this website. By creating an account or using the Service, you agree to these Terms. If you don't agree, don't use the Service.

1. Eligibility

You must be at least 13 years old to use Columnam. If you are under 18, you confirm that a parent or legal guardian has reviewed and agreed to these Terms on your behalf.

2. What Columnam is

Columnam is a focus-training tool. It helps you plan deep focus sessions, measures your session activity over time, and adapts its guidance based on that history. It is a productivity aid, not a medical, psychological, or educational service, and it does not guarantee any particular outcome — academic, professional, or otherwise.

3. Accounts

You're responsible for keeping your login credentials secure and for all activity under your account. Tell us right away if you suspect unauthorized use. We may suspend or terminate accounts that violate these Terms or that we reasonably believe are being used fraudulently or abusively — and, more broadly, we may refuse, suspend, or terminate service as described in Section 14.

4. Membership, billing, and automatic renewal

Paid membership is sold on the web, not through the iOS app. Payments are processed by Stripe; we never see or store your full card number.

Automatic renewal. Membership is an automatically renewing subscription. When you subscribe, you give your express affirmative consent to the renewal terms presented at checkout, and:

• Your membership automatically renews at the end of each billing period (the interval you selected — e.g., monthly or annually) and your payment method is charged the then-current fee until you cancel.
• The length of the term and the renewal charge amount and frequency are shown to you before you complete purchase and in your checkout confirmation.
• If any free trial or promotional period applies, it converts to a paid, auto-renewing membership at the stated rate when it ends unless you cancel first; we will send any advance conversion notice required by law.
• If we change the recurring fee, we will notify you in advance — at least 7 and no more than 30 days before the new fee takes effect — along with how to cancel.

5. Cancellation and refunds

You can cancel at any time, online, at will. Because you signed up online, you may cancel online through your account or the Stripe billing portal linked from it, without calling us, without a retention process, and without any step that obstructs or delays cancellation. Cancellation stops future renewals; it takes effect at the end of the current billing period, and you keep access until then.

• Fees already paid are non-refundable except where required by law or expressly stated otherwise at checkout.
• Canceling does not delete your account or data — you can continue using any free portion of the Service. To remove your data, delete your account (see Section 15) or contact us.

6. Acceptable use

Don't misuse the Service. That includes, without limitation: attempting to access accounts or data that aren't yours, reverse-engineering or scraping the app or site, interfering with normal operation, or using the Service for anything unlawful.

7. Your content

You keep ownership of what you enter into the Service (your quiz answers, class names, goals, and similar inputs). You grant us a license to store, process, and use that content solely to operate, maintain, and improve the Service for you — see our Privacy Policy for details on how your data is handled.

8. Intellectual property

Columnam, its design, branding, and underlying software are owned by us or our licensors and protected by applicable intellectual property laws. Using the Service doesn't give you any ownership rights in it.

9. Disclaimers

The Service is provided "as is" and "as available," without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. We don't warrant that the Service will be uninterrupted, error-free, or that any measured improvement in focus will occur or persist. Some jurisdictions don't allow the exclusion of certain warranties, so some of these exclusions may not apply to you.

10. Limitation of liability

To the fullest extent permitted by law, Columnam and its owners, officers, and agents aren't liable for indirect, incidental, special, consequential, or punitive damages, or for any loss of data, revenue, or opportunity arising from your use of the Service. Our total liability for any claim relating to the Service is limited to the greater of the amount you paid us in the twelve months before the claim arose or one hundred U.S. dollars (US$100). Some jurisdictions don't allow certain limitations, so parts of this section may not apply to you.

11. Indemnification

You agree to indemnify, defend, and hold harmless Columnam and its owners, officers, and agents from and against any claims, damages, losses, liabilities, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your use or misuse of the Service; (b) your violation of these Terms; (c) your violation of any law or the rights of a third party; or (d) content you submit to the Service.

12. Dispute resolution — arbitration and class-action waiver

Please read this section carefully — it affects your legal rights.

Informal resolution first. Before filing a claim, you agree to try to resolve the dispute informally by emailing info@columnam.com and giving us 30 days to work it out.

Binding arbitration. If we can't resolve a dispute informally, you and Columnam agree that any dispute arising out of or relating to these Terms or the Service will be resolved by final and binding individual arbitration administered under the rules of a recognized arbitration provider, rather than in court, except that either party may bring an individual claim in small-claims court. This agreement is governed by the Federal Arbitration Act.

Class-action waiver. You and Columnam agree that each may bring claims against the other only in your or its individual capacity, and not as a plaintiff or class member in any purported class, collective, or representative proceeding. The arbitrator may not consolidate more than one person's claims.

Opt-out. You may opt out of this arbitration and class-action-waiver section within 30 days of first accepting these Terms by emailing info@columnam.com with your account email and a statement that you opt out. If you opt out, disputes proceed in the courts identified in Section 16.

13. Community content and conduct

Parts of Columnam let you post content other members can see: a profile photo, and a one-line summary of a day you choose to share. Posting is always optional and nothing is shared unless you turn sharing on.

There is no tolerance for objectionable content or abusive behaviour. By posting, you agree not to upload or share anything that is unlawful, hateful, harassing, threatening, defamatory, sexually explicit, violent, deceptive, or that infringes someone else's rights — including a profile photo that is not yours to use or that depicts another person without their agreement.

Every piece of member-visible content can be reported from the menu on the post itself, and profile photos can be reported the same way. Content reported by three separate members is removed automatically. You can also block any member, which removes their posts and their photo from your view.

If three separate pieces of your own content are removed this way — any mix of shared days, success stories, or your profile photo — your Community access is suspended automatically: you can no longer post, react, or be grouped with others there. This never affects your paid membership or the rest of the app. We may also suspend or remove content or access outside this threshold, without notice and at our discretion, where we believe it's warranted. If you believe a suspension was a mistake, email the contact address in Section 18 to ask for a review; we aim to respond within 24 hours.

14. Termination and refusal of service

You may stop using the Service and delete your account at any time from Account settings.

We may refuse, suspend, or terminate service to anyone, at any time, for any reason or no reason, at our sole discretion, and we may decline to provide the Service to any prospective or existing user. This includes, but is not limited to, violations of these Terms or conduct we believe is fraudulent, abusive, or harmful — but it is not limited to cause. We may do so with or without notice. To the extent we terminate a paid membership without cause, we will refund the unused, prepaid portion of your then-current billing period; no refund is owed where we terminate for your breach of these Terms.

Nothing in this section permits us to refuse service for a reason prohibited by applicable law (for example, unlawful discrimination). On termination or deletion, your data is removed per our Privacy Policy. Sections that by their nature should survive termination — including Sections 8 through 12 and 15 through 16 — will survive.

15. Account deletion

You can delete your account and associated data at any time from Account settings in the app, or by contacting us. Deletion is handled as described in our Privacy Policy. Deleting your account does not by itself cancel a paid subscription if one is active — cancel first (Section 5) to stop future charges.

16. Changes and governing law

We may update these Terms from time to time. If we make material changes, we'll post the updated Terms here with a new "Last updated" date. Continuing to use the Service after changes take effect means you accept the updated Terms.

These Terms are governed by the laws of the United States of America and, to the extent state law applies, the state in which Columnam is organized, without regard to conflict-of-law principles. The Service is intended for use within the United States; we make no representation that it complies with the laws of any other country.

17. Miscellaneous

These Terms, together with the Privacy Policy, are the entire agreement between you and Columnam regarding the Service and supersede any prior agreements. If any provision is found unenforceable, the rest remains in effect and the unenforceable provision is limited to the minimum extent necessary. Our failure to enforce a provision isn't a waiver of it. You may not assign these Terms without our consent; we may assign them in connection with a merger, acquisition, or sale of assets. We aren't liable for delays or failures caused by events beyond our reasonable control.
