Dayline Terms of Service

The plain summary

• Dayline is a personal log: you tell it what happened, and it keeps your entries, spending, health notes and plans organised. Your stored entries are encrypted on your devices; see the Privacy Policy.
• You keep your keys. If you lose all your devices, your passkeys and your recovery key, we can't recover your data.
• The AI can get things wrong. Check what it logs. Dayline doesn't give medical, financial, legal or tax advice.
• Dayline is in beta, and features may change. While it's in beta it is free for everyone. You can subscribe to Plus early to support it: it renews monthly or yearly until you cancel, your price stays the same for as long as you stay subscribed, and you can cancel at any time in Settings and keep it until the end of the period you paid for. Free stays free.
• If you don't sign in with Google for 12 months, we delete your account, after an email warning 30 days before.

1. Who we are and this agreement

These terms are an agreement between you and Sahil Singh, an individual in India who runs Dayline ("we", "us"), about the Dayline app and website at dayline.online and the Dayline Android app (the "service"). Our contact details are in section 13. You accept these terms by ticking "I accept the Terms" on the sign-in screen before you create an account; we record which version of the terms you accepted and the day. How we handle your data is explained in the Privacy Policy: accepting these terms is not consent to any use of your data, and the choices the policy describes (such as the AI mode, which you choose separately when you set up Dayline, and usage counts) stay yours to change at any time. If you don't accept these terms, don't use Dayline.

You must be 18 or over to use Dayline: the sign-in screen asks you to confirm it before an account is created. Dayline is for your personal use, not for a business.

Where Dayline is available. Dayline is not offered in the European Union, the other EEA countries (Iceland, Liechtenstein, Norway), the United Kingdom or Switzerland. New accounts can't be created from those countries (we go by the country Cloudflare's network places your connection in, which we don't store). If you already have an account, it keeps working when you travel.

2. What Dayline is

Dayline turns what you type or say into a structured log on your devices: entries, money, health, people, places, plans and day stories. Entries are encrypted on your device before they sync between your devices through our servers. Optional AI features interpret your messages; how and where that happens depends on the AI mode you choose, as the Privacy Policy explains.

Dayline is a personal record-keeping tool. It is not a medical device, and nothing in it is medical, financial, investment, legal or tax advice. Totals, summaries and stories are only as accurate as what was logged and how it was interpreted. Don't rely on them for decisions that need professional advice, and in an emergency contact your local emergency services.

Beta. Dayline is in beta. Features may change, have bugs, or be removed while we learn what works. During the beta, accounts may get Plus features for free until an end date that the app shows; we tell you in the app 14 days and 3 days before it. After that date such an account moves to Free unless you subscribe, and nothing you logged is deleted. We take payments only once paid plans are switched on; the plan screen says whether they are.

Subscribing during the beta (early supporters). While the beta lasts, everyone gets Plus features for free, and you may still subscribe to Plus, monthly or yearly, to support Dayline. It is a paid plan like any other: you pay the price shown before you pay, it renews automatically until you cancel, and section 6 and the Refund & Cancellation Policy apply to it in full. During the beta it doesn't unlock extra features (your AI allowance is Plus's own where that is more than the beta's). In return:

• Your price is locked. Your subscription renews at the price you started it at for as long as it keeps renewing without a break, even if we charge new subscribers more (the "Price changes" point in section 6 doesn't apply to it). If we register for GST, that same total includes the GST. If you cancel, or the subscription stops because every renewal payment failed, and you subscribe again later, the price at that time applies.
• No break when the beta ends. Your Plus plan simply continues; the move to Free described above doesn't apply to you while you're subscribed.
• If your subscription ends during the beta (you cancel, or every renewal payment fails), you keep Plus until the end of the period you paid for, then you're back on the free beta like everyone else.
• In Settings you're shown as a supporter while your subscription is paid for.

3. Your account and your keys

• You sign in with a Google account (beta accounts made with an emailed code through Cloudflare Access continue as the same account when you sign in with Google using the same email). Signing in proves who you are; it doesn't unlock your data. Your data is unlocked by a passkey, one of your devices, or your recovery key.
• You are responsible for keeping at least one way back in: a saved recovery key, a passkey, or another device. We don't have your keys and can't reset them. If you lose every one of them, your stored data can't be opened by you or by us.
• Someone who controls your Google account can schedule a reset that erases your stored data after 7 days unless one of your devices cancels it. Keep your Google account secure, and watch your devices and your email (we email you when a reset is scheduled) for it.
• One account is for one person. Don't share it or sign in to someone else's.
• Tell us at support@dayline.online if you think someone else has used your account.

4. Your content

• What you log is yours. We claim no ownership of it.
• You give us only the permission we need to run the service for you: to store and sync the encrypted copies of your data, and, when you use an AI mode that sends text to an AI model, to pass that text to the model for that request. This permission ends when you delete the content or your account. We don't use your content to train AI models and we don't sell it.
• We can't read your stored entries, so we don't review them. You are responsible for what you put in Dayline and for having the right to log information about other people.
• You can export or delete your data in the app at any time (Settings: Export, Privacy & security, and Delete account at the foot).
• If you send us feedback or ideas, we may use them to improve Dayline without owing you anything for them. An entry you include in a report is used only to look into that report.

5. AI features

• AI output can be wrong, incomplete or out of date: an amount, a date, a person or a category can be misread, and a story or review can say something that didn't happen. Review what Dayline logs and correct it.
• In Standard AI mode, your message and related context are processed in plaintext by our server and our AI provider for each request. This is described in the Privacy Policy and is protected by policy and contract, not by encryption. You can switch to On-device only at any time.
• Each plan includes a monthly amount of AI use (commands and day stories), shown in the app. When it runs out, AI features pause until the next period, or until you add a top-up where top-ups are offered. Dayline keeps working without AI: its built-in rules log your entries on your device.
• "Private AI" is shown as coming soon. It is not part of any plan you can buy today.

6. Plans, payment, renewal and cancellation

• Free costs nothing and has the limits shown in the app. Paid plans (and top-ups, where offered) are described, with their prices, on the plan screen at the time you buy. Prices in India include GST where it applies; elsewhere taxes are shown at checkout. The total you'll pay, and whether it renews, are shown before you pay. We send a receipt, and a tax invoice where the law requires one, for each payment.
• Payments are handled by Razorpay (Razorpay Software Private Limited, India), our payment processor, on its own secure page, by UPI AutoPay or card. We never see your card or UPI details. Razorpay's terms apply to the payment itself, and its receipts and invoices are listed on the Support page in the app (/support).
• GST. We are not registered for GST, so no GST is charged and the price on the plan screen is the full amount you pay. If we register, prices will include GST, your invoices will show it and our GSTIN, and we'll update these terms first.
• Paid plans renew automatically at the end of each monthly or yearly period, at the price you agreed, until you cancel. Before each renewal charge on an Indian card or UPI, you get the notice India's recurring-payment rules require (at least 24 hours before the charge), and you can cancel then. We remind you at least 7 days before a yearly plan renews.
• Free trials, if we offer one, show the day the trial ends and the price after it before you start, and we remind you before the first charge. Cancel before that day and you pay nothing.
• You can cancel at any time on the Support page in the app, /support (Cancel plan, then confirm), in as few steps as it took to subscribe. Cancelling stops the next renewal; you keep the paid plan until the end of the current period. The Refund & Cancellation Policy has the details.
• Price changes apply only from your next period and only after we tell you at least 30 days before. If you don't agree, cancel before the change applies. A subscription started during the beta keeps its price (section 2, "Subscribing during the beta").
• Refunds. If something we did stopped the service from working for you, write to us and we'll refund or credit you fairly. Refunds go back to the way you paid. Unused parts of a period are otherwise not refunded, and top-ups are not refunded once used, except where these terms or the law say otherwise. If you live in the EU or UK you have a 14-day right to withdraw from a purchase without giving a reason; by starting a paid plan straight away you ask us to begin the service during that period, and if you then withdraw we refund what you paid minus an amount in proportion to the part of the service already provided. How to ask, and how long a refund takes, is in the Refund & Cancellation Policy.
• Deleting your account cancels a paid plan at once.

7. Acceptable use

Don't use Dayline to break the law, or to:

• try to get into another person's account or data, or test, probe or overload our systems without our written permission (security research: write to security@dayline.online first and we'll work with you);
• use the AI features to generate content for anyone other than yourself, resell access, or get around the plan limits with automated or multiple accounts;
• reverse-engineer the service to harm it or its users. (Inspecting the code your browser receives and checking it against /verify is welcome.)

We may limit or suspend an account that does these things. Because your data is encrypted, we act on what we can see (for example request rates or payment fraud), not on your content.

8. The service, changes and availability

• We work to keep Dayline available and your data safe, but we don't promise it will always be available or free of errors. Keep an export of anything you can't afford to lose.
• We may change, add or remove features. If we remove something important from a paid plan during a period you've paid for, we'll tell you and offer a fair refund or credit.
• If we ever decide to shut Dayline down, we'll tell you at least 60 days before, keep export working until then, and refund the unused part of any paid period.
• We aren't responsible for a failure or delay caused by events outside our reasonable control (for example a major outage at our hosting provider, a natural disaster or a government order). We'll tell you, keep the effect as small as we can, and if it lasts more than 30 days you can cancel and get a refund for the unused part of a paid period.

9. Inactive accounts

If you don't sign in with Google for 12 months, we delete your account and everything stored in it, and we can't restore it. We email you 30 days before; we don't delete an account we couldn't warn.

10. Ending this agreement

• You can stop at any time by deleting your account in the app. That deletes your stored data as described in the Privacy Policy.
• We may suspend or close an account that seriously or repeatedly breaks these terms, or where the law requires it. Except for fraud, abuse or a legal order, we'll tell you first, explain why, and give you time to export your data. If we close a paid account without it being your fault, we refund the unused part of the period. You can write to us (section 13) if you think we got it wrong.

11. Our responsibility to you

• Nothing in these terms limits or excludes: a right you have as a consumer that the law of your country doesn't allow to be limited (for example, in the EU and UK, your rights when digital content or a digital service isn't as described); our liability for death or personal injury caused by our negligence; or our liability for fraud, for harm we cause on purpose or through gross negligence, or for anything else the law doesn't allow us to limit.
• Otherwise, Dayline is provided "as is" and, during the beta, "as available". We are not liable for losing data that can't be recovered because you lost every way back in (section 3: by design, we can't open it), for losses caused by the AI misreading a message you didn't check, or for losses that weren't reasonably foreseeable when you started using Dayline.
• Otherwise, our total liability to you for all claims about the service is limited to the greater of the fees you paid us in the 12 months before the claim and ₹1,000.

12. Law and disputes

These terms are governed by the laws of India. Courts at New Delhi, India have jurisdiction, but if you live elsewhere you can also bring a claim in your own country and keep the protection of its mandatory consumer laws. In India you can also go to the Consumer Commission where you live or work, under the Consumer Protection Act 2019 (including online through e-Daakhil) or call the National Consumer Helpline (1915). These terms have no arbitration clause and no waiver of class or group claims. Please write to us first: most problems can be solved quickly.

14. Changes to these terms

We'll tell you in the app at least 30 days before a material change takes effect. If you don't agree, you can cancel and delete your account before then; if you do that during a period you've paid for, we refund the unused part. Continuing to use Dayline after the change takes effect means you accept the new terms.

15. Other terms

• Notices. We contact you in the app or at your account's email address; you can reach us at the addresses in section 13.
• Transfer. We may transfer this agreement to someone who takes over Dayline, only if they keep these terms and the Privacy Policy's promises; we'll tell you first, and you can delete your account if you don't agree. You may not transfer your account.
• The whole agreement. These terms and the Privacy Policy are the whole agreement between us about Dayline. If a court finds part of them invalid, the rest still applies. If we don't enforce a term straight away, we can still enforce it later.
• Translations. If a translation of these terms differs from this English text, the English text applies, unless the law where you live says otherwise.
