Terms of Service

Last updated: October 14, 2026 · Effective immediately

Please read these Terms carefully before using ShouldISail. By accessing or using the Service — on any platform, including web and mobile — you agree to be bound by them. If you do not agree, do not use the Service.

1. Who We Are

ShouldISail ("Service", "we", "us") is operated by Eran Yanikov, an individual based in Israel. Contact: info@shouldisail.com.

2. What the Service Does

ShouldISail provides sailing condition assessments and related maritime planning tools across web and mobile platforms. Features include, but are not limited to:

Weather & Conditions: 9-day hourly marine forecasts (wind, gust, wave, swell, current, visibility, precipitation) for any point at sea, powered by StormGlass data.
Sailing Suitability Assessment: A plain-language verdict (Yes / Challenging / Requires Safety Gear / Only if You Must / No) tailored to your selected vessel type.
Route Planner: Draw multi-waypoint routes, receive per-segment sailing-suitability scores based on forecast departure times, and view estimated distances and travel times.
Saved Routes & Favorite Spots: Persistently store named routes and bookmarked sea locations (Pro tier).
Live GPS Navigation (mobile): Real-time position and compass heading displayed on the chart, speed over ground (SOG), and a nautical chart overlay (OpenSeaMap).
Track Recording (mobile): Background GPS track recording that survives app suspension; automatic stop on reaching land; post-trip summary; ability to convert recorded tracks to saved routes (Pro tier).
Anchor Watch (mobile): Set an anchor position and chain length; the app monitors your position in the background and triggers an alarm if your boat moves outside the calculated swing radius.
Sea Depth Information: Approximate water depth at a tapped or anchored location, sourced from the GEBCO global bathymetry database.

All assessments and calculations are informational only. See Sections 7 and 8 for critical safety limitations.

3. Eligibility and Accounts

You may use the Service as a guest (limited free lookups) or as an authenticated user by signing in with your Google or Apple account.

You must be at least 18 years old to purchase a paid subscription. Users under 18 may use the free tier with parental consent.
You are responsible for keeping your account credentials secure.
Each account must represent one individual person. Creating multiple accounts to circumvent quota limits, refund policies, or any other restriction is strictly prohibited and constitutes a material breach of these Terms.
You may not use the Service for automated scraping, bulk data collection, or any commercial redistribution of data obtained from the Service.

4. Subscriptions and Payments

The Service offers a single paid tier:

Pro Plan — $50 USD per year, which removes the daily weather-lookup quota and unlocks route saving, saved spots, track recording, anchor watch, and any future premium features.

Payments are processed by Paddle (paddle.com), which acts as the Merchant of Record for all transactions. When you purchase a subscription, your contract of sale is with Paddle, and Paddle's own Terms of Use and Privacy Policy also apply to your purchase. Paddle handles all applicable taxes (including VAT/GST) on our behalf.

Your subscription auto-renews annually. You will receive a renewal reminder at least 7 days before the renewal date. You can cancel at any time from your account settings; cancellation takes effect at the end of the current billing period.

iOS (App Store) Subscribers

If you subscribe through the iOS App Store, your purchase is processed by Apple, not Paddle. The following terms apply to Apple In-App Purchase subscriptions:

Subscription name: ShouldISail Pro
Duration: 1 year (auto-renewing)
Price: As displayed in the App Store for your region at the time of purchase.
Payment is charged to your Apple ID at confirmation of purchase.
The subscription automatically renews unless cancelled at least 24 hours before the end of the current period.
Your account will be charged for renewal within 24 hours prior to the end of the current period at the same price.
To cancel, go to Settings → [your name] → Subscriptions on your iOS device. You will retain Pro access until the end of the paid period.
Refunds for App Store purchases are handled by Apple in accordance with their policies. We cannot issue refunds for Apple-billed transactions directly.
Apple, not Paddle, acts as the Merchant of Record for iOS purchases. Apple’s Standard EULA applies to your purchase in addition to these Terms.

Partner Codes and Bonus Months

Some sailing clubs, schools, shops and other partners hand out a partner code. If you enter a valid partner code on the upgrade screen before your first Pro purchase, you receive two (2) free months of Pro, added after your paid year.

Web (Paddle) subscriptions: the bonus months are added by moving your next renewal date. You are not charged for them.
App Store and Google Play subscriptions: Apple and Google set the renewal date, and we cannot change it. We keep the bonus months in reserve, and they start on the day your store subscription ends (when you cancel or it does not renew). While you keep renewing, the bonus months stay in reserve. During the bonus months there is no store subscription to manage, renew or cancel. Pro simply ends on the date shown in your account.
A partner code applies only to the first paid Pro subscription of an account. It cannot be used by an account that already has or previously had Pro. Each account can use one partner code, once. The code must be entered before the purchase and cannot be added afterwards.
A partner may not use its own code. Bonus months have no cash value, cannot be transferred, exchanged or refunded, and cannot be combined with another partner code.
If your first payment is refunded (including under the 3-day money-back guarantee) or charged back, any bonus months that have not yet started are cancelled, and any bonus period already running may be ended.
We may decline, withdraw or cancel a partner code or bonus months in case of abuse, fraud, a code obtained in breach of these Terms, or an obvious error. We may change the number of bonus months or end partner codes for future purchases at any time. Bonus months already confirmed are kept.
Partners are independent third parties, not our agents. A partner cannot make promises on our behalf or change these Terms.

5. Cancellation and Refunds

You may cancel your subscription at any time via your account settings or by contacting us at info@shouldisail.com.

3-Day Money-Back Guarantee

We offer a 3-day (72-hour) money-back guarantee subject to all of the following conditions:

The guarantee applies only to the initial subscription purchase per person. Annual automatic renewals are not eligible for a refund under this guarantee.
One refund per person, ever. A refund may be issued at most once per individual, identified by — but not limited to — any combination of: registered email address, payment method, device identifier, IP address, or name. We reserve the right to use any available signal to determine whether a refund has previously been issued to the same person under a different account. Re-subscribing after receiving a refund and requesting another refund constitutes abuse of this policy and will be declined.
The 72-hour window is calculated from the UTC timestamp of the original transaction as recorded by Paddle, not from when you first open the app or access your account.
No refund if Pro features have been substantially used. Substantial use includes, but is not limited to: saving three or more routes, performing three or more route weather analyses, storing three or more Favorite Spots, or conducting active Anchor Watch sessions. Determination of substantial use is at our sole and reasonable discretion.
A refund will not be issued if we have reasonable grounds to believe the request is fraudulent, abusive, or part of a pattern of refund abuse across any accounts.
To request a refund, email info@shouldisail.com within the 72-hour window. Your email must include: (a) your registered account email address, (b) your Paddle order ID as shown on your receipt, and (c) a brief reason for your request. Incomplete requests will not be processed.

Cancellations Outside the Guarantee Window

Cancellations made after the 3-day window are not eligible for a refund. You will retain full Pro access until the end of the current paid billing period.
Approved refunds are typically processed by Paddle within 5–10 business days.

Statutory Consumer Rights

Israeli users also benefit from cancellation rights provided under the Israeli Consumer Protection Law (5741-1981) and its regulations, to the extent applicable to digital services.

If you are located in the European Economic Area: EU consumers have a statutory 14-day right of withdrawal from distance contracts. However, under Article 16(m) of Directive 2011/83/EU, this right is waived for digital content not delivered on a tangible medium once the consumer has expressly consented to the performance commencing before the end of the withdrawal period and acknowledged the loss of that right. By completing your purchase and accessing any Pro feature, you expressly consent to immediate performance and acknowledge that you waive the 14-day right of withdrawal. Our 3-day guarantee is offered in addition to — and does not replace — any statutory right that cannot lawfully be waived under your local law.

Nothing in this section limits any statutory consumer rights that cannot be excluded by contract under the laws of your country of residence.

6. Free Tier Limits and Pro Days

Guest (unauthenticated) users and free registered users may make a limited number of weather lookups per day (UTC) ("Quota"). Guest lookups are counted per device network address, and free registered users per account. The current Quota is shown in the Service. We may change the Quota at any time with reasonable notice.

Pro Days (free trial)

New registered accounts receive a number of free Pro Days. The number and the length of a Pro Day are shown in the Service; currently new accounts get 3 Pro Days, each lasting 24 hours.

A Pro Day starts only when you choose to start it. From then on it unlocks all Pro features for its full length, whether or not you use the Service during that time. A started Pro Day cannot be paused, moved or returned.
Pro Days are granted once, when the account is created. They are free, require no payment details, and never turn into a paid subscription on their own. They have no cash value and cannot be transferred, exchanged or refunded. Creating additional accounts to obtain more Pro Days is prohibited (see Section 3).
Routes, spots, alerts and other items you saved during a Pro Day stay in your account. You can still view and delete them. Creating or editing them again requires a Pro subscription or another Pro Day.
Pro Days are not available while you have an active Pro subscription. We may change the number or length of Pro Days for accounts created in the future, or end the trial, at any time. Pro Days already granted to an account are kept.

7. Safety Disclaimer — Critical Warning

ShouldISail is an informational and planning tool only. It is NOT a certified navigational aid, NOT a substitute for professional maritime judgment, and NOT a life-safety system. Do not rely solely on this Service to make any decision at sea.

Weather conditions at sea can change rapidly and without warning. The assessments provided by ShouldISail are derived from third-party forecast data (StormGlass) that may be inaccurate, incomplete, delayed, or unavailable. No weather model or algorithm can guarantee accuracy of real-world sea conditions.

You assume full and sole responsibility for all decisions you make regarding sailing, navigation, anchoring, or any other activity at sea. Before undertaking any sailing activity, you must independently verify conditions through official maritime weather services, harbour masters, coast guard advisories, and your own first-hand observation.

We accept no liability whatsoever for any injury, loss of life, vessel damage, property damage, or any other harm — direct or indirect — arising from any decision made based wholly or partly on information provided by this Service.

8. Feature-Specific Safety Notices

The following notices apply to specific features of the Service and form part of the Safety Disclaimer in Section 7.

8.1 Weather Assessments & Sailing Suitability

Sailing suitability verdicts are generated by an algorithm based on configurable thresholds. They are intended as a general starting point for planning only. The algorithm does not account for local topographic effects, tidal currents, combined sea states, your personal skill level or physical condition, the condition of your vessel or safety equipment, or any factor not represented in the source weather data. A verdict of "Yes" or "Challenging" does not mean it is safe or appropriate for you to sail.

8.2 Route Planner

Route distance, estimated travel time, and per-segment weather scores are approximations. ETA calculations assume constant cruising speed and do not account for tacking, currents, wind-driven leeway, stops, or real-time deviations. The land-crossing detection feature is not a substitute for proper chart work. Do not use the route planner as your sole basis for voyage planning.

8.3 Live GPS Navigation (Mobile)

The live position, compass heading, and speed-over-ground display rely on your device's GPS and sensors, which may be inaccurate, drift, or lose signal without warning. This feature is not a certified chart plotter and must not be used as your primary or sole means of navigation. Always carry and use properly certified nautical charts and navigation instruments. The operator accepts no responsibility for navigational errors arising from use of the in-app GPS display.

8.4 Track Recording (Mobile)

Track recording relies on background device GPS services, which may be interrupted, delayed, or terminated by the operating system at any time. The "auto-stop on land" feature depends on GPS accuracy and may not activate correctly in all circumstances. Recorded distance and speed figures are estimates derived from GPS sampling intervals and are not guaranteed to be accurate. Do not use recorded track data for official maritime log or legal purposes.

8.5 Anchor Watch (Mobile)

The Anchor Watch feature is a supplementary notification tool only. It is not a certified maritime safety product and must not be treated as one.

The drag-detection alarm relies on your device's GPS, which may be inaccurate, delayed, or fail entirely due to poor signal, battery state, operating-system restrictions, or other factors outside our control.
The app may be suspended or killed by the operating system, silencing the alarm without warning, regardless of the crash-recovery mechanism.
The swing-radius calculation is based on the chain length and depth values you enter and assumes a simplified model; actual swing radius may be larger or smaller depending on seabed conditions, wind, vessel windage, and other variables.
Sea depth figures used in scope calculations are sourced from the GEBCO global bathymetric dataset, which provides low-resolution averaged data; actual depth at your location may differ significantly, especially in shallow, coastal, or dredged areas.
You must never leave your vessel unattended relying solely on this app as your anchor alarm. Always maintain proper watch procedures in accordance with good seamanship and applicable regulations (COLREGs or local law).

8.6 Sea Depth Information

Depth values displayed in the app are sourced from the GEBCO global bathymetry database, which provides low-resolution averaged data and is not a substitute for official hydrographic charts. Depth values may be significantly inaccurate in coastal, harbour, or estuarine areas. Do not use app-displayed depth values for anchoring, berthing, or any decision where accurate water depth is critical to safety.

8.7 Nautical Chart Overlay

The nautical overlay displayed in the app is provided by OpenSeaMap and is crowd-sourced. It is not an official maritime chart and must not be used for navigation. Always consult official, up-to-date Admiralty or equivalent national hydrographic charts for navigation.

9. Data We Collect and How We Use It

We collect the following categories of data:

Account Data (authenticated users): Your name and email address, obtained via Google OAuth 2.0 or Apple Sign-In, solely for the purpose of creating and identifying your account. We do not access your Google Drive, Gmail, contacts, calendar, or any other Google or Apple account data beyond what is required for authentication.
Location Data (mobile): GPS coordinates collected during live navigation, track recording, and anchor watch. Location data is processed on-device and transmitted to our servers only where necessary (e.g., to fetch weather for a tapped location or to save a route). We do not continuously stream your raw GPS track to our servers in real time.
Usage Data — Sailing Lookups: The geographic coordinates you request weather for and the resulting assessments. This data is stored to enforce quotas, display your history, and improve the Service.
Saved Content: Routes, Favorite Spots, and preferences you choose to save, stored server-side so they are accessible across devices.
Payment Data: We do not store your payment card details. All payment information is handled exclusively by Paddle. We receive only a transaction confirmation and subscription status.
Technical / Log Data: IP addresses, browser or app version, device type, and error logs, retained for security and debugging purposes.

We do not sell your data to third parties. We do not use your data for advertising profiling. We process your data under Israeli Privacy Protection Law (5741-1981). If you are located in the European Economic Area, we process your data on the legal basis of contract performance (Article 6(1)(b) GDPR) and legitimate interests (Article 6(1)(f) GDPR). You have the right to access, correct, and request deletion of your personal data.

To request deletion of your account and associated data, email info@shouldisail.com.

12. Disclaimers and Limitation of Liability

The Service is provided "as is" and "as available" without any warranty of any kind, express or implied, including but not limited to merchantability, fitness for a particular purpose, or non-infringement.

To the maximum extent permitted by applicable law, the operator of ShouldISail shall not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, including but not limited to loss of profits, data, goodwill, or life, arising out of or in connection with your use of — or inability to use — the Service, even if advised of the possibility of such damages.

Nothing in these Terms excludes or limits liability that cannot lawfully be excluded or limited in your jurisdiction, including liability for death or personal injury caused by negligence, or for fraudulent misrepresentation.

13. Intellectual Property

All content, design, source code, and branding of ShouldISail are the exclusive property of the operator of ShouldISail. You are granted a limited, non-exclusive, non-transferable, revocable licence to use the Service for personal, non-commercial purposes only. You may not copy, modify, distribute, sublicense, or create derivative works of any part of the Service without our prior written consent.

14. Modifications to the Service and Terms

We reserve the right to modify, suspend, or discontinue any part of the Service at any time. We may also update these Terms from time to time. Material changes will be communicated via email (for registered users) or a notice within the Service at least 14 days before taking effect. Continued use of the Service after the effective date constitutes acceptance of the revised Terms.

15. Governing Law and Disputes

These Terms are governed by and construed in accordance with the laws of the State of Israel, without regard to conflict-of-law principles. Any dispute arising out of or in connection with these Terms shall be submitted first to good-faith negotiation between the parties. If unresolved within 30 days, the dispute shall be subject to the exclusive jurisdiction of the competent courts located in Israel.

Nothing in this clause limits your rights as a consumer under the mandatory consumer protection laws of your country of residence, including the right to bring claims before courts or consumer tribunals in your own country where such right cannot be contractually waived.

16. Partner Programme

This section applies to clubs, schools, shops, marketers and other organisations or individuals we accept as partners ("Partner") and to whom we issue one or more partner codes. Section 4 (Partner Codes and Bonus Months) describes what users receive.

Payout. We pay the Partner a fixed amount for each user who becomes Pro for the first time using one of the Partner's codes. The amount is currently USD 10 per user, unless we agree a different amount with you in writing. The amount is fixed when that user's first payment is confirmed. It is paid once per user. Renewals and later payments by the same user earn nothing.
Hold period. A user counts only after a 30-day hold from their first payment, and only if they still have an active Pro subscription at the end of the hold. No payout is due for users who are refunded, charge back, cancel with a refund, or are no longer Pro at the end of the hold. If a refund or chargeback happens after a payout became due, we may withdraw it or deduct it from a later payout.
Monthly statement and payment. We prepare a statement each calendar month (UTC) of the users who became payable that month, identified by an anonymous user number, date and platform. We do not share users' names or email addresses. Payment is made after the statement, by the method agreed with you, in USD unless agreed otherwise. You are responsible for any taxes, invoices and registrations required for the payments you receive. Our records of codes, payments and refunds are final, unless they contain an obvious error.
Conduct. You may promote your code honestly to people who may want the Service. You may not:
- use your own code or ask people close to you to subscribe only to earn a payout;
- create or encourage fake, duplicate or self-referred accounts;
- offer cash or other rewards in return for using your code, unless we agree in writing;
- send spam;
- bid on our name in paid search ads;
- misrepresent the Service, its prices, its safety features or your relationship with us.
You may not make promises on our behalf.
Voiding and termination. We may void payouts linked to abuse, fraud or a breach of this section, and deactivate a Partner's codes. We may also change the payout amount for future users, or end the Partner Programme, with reasonable notice to the Partner. Payouts for users already confirmed before the change are still paid under the terms in force when they were confirmed, unless voided under this section.
Relationship. Partners are independent. Nothing in this section creates an employment, agency, partnership or joint-venture relationship, and a Partner may not bind us.
