Terms of Use

Last updated November 4, 2026

These terms of use ("these terms") are the agreement for using Crayon Plants (クレヨンプランツ, its Apple Watch app included, "the app"), a houseplant watering reminder made by Takaki Takemura, an individual developer in Japan ("we"). By downloading or using the app, you agree to these terms.

The terms of the store you got the app from apply as well: from the App Store, Apple's Licensed Application End User License Agreement (except where these terms say otherwise); from Google Play, the Google Play Terms of Service.

Licence

As long as you keep to these terms and to your store's, we give you a personal, non-exclusive, non-transferable right to use the app on devices you own or control. The app's pictures, words and code belong to us or to their rightful owners.

Your plants and records

Your plants, your watering and care logs, your albums' photos, your rooms and your settings are kept on your device (and in your device's own backup). Deleting the app or resetting the device removes them. You can take them to a new phone with Move to a new phone; beyond that, we cannot bring data back.
Watering reminders depend on your device's notification settings, battery and the like, and may come late or not at all. Look at your plants and decide their care yourself.
Please do not put your real name, address or anything else that identifies you in plants' names, nicknames or notes.

Make it from a photo, and asking about the leaves

When you make a plant from a photo, or ask about a plant's leaves, the photo you choose (and, for a question, what you write) is sent through our server to Claude, Anthropic's AI. Our Privacy Policy says more. Please leave people's faces and anything private out of your photos.
An answer about the leaves is an AI's guess from one photo, not a diagnosis. It may be wrong, or miss something important. Whether to follow it is your decision; if a plant you treasure suddenly gets worse, ask a garden centre or a plant expert too. If a person or a pet has eaten a plant or feels unwell, do not rely on the app: see a doctor or a vet straight away.
What the app says about plants that are toxic to pets is a guide drawn from published sources. It does not cover every plant or every symptom.
Making plants from photos and asking about the leaves are not offered in mainland China. They may not be available when the service is busy or a day's limit is reached (nothing is used up then).

Purchases

Apple takes payment on the App Store, and Google on Google Play, under each store's rules. The price is the one shown where you buy.
Pro (paid once) and what you buy in the shop are yours to keep. Restore purchase brings them back with the same store account.
Photo tickets are used up (one plant from a photo, or one question about the leaves; they do not expire). None is used if no drawing or answer comes. Tickets used do not come back, and Restore purchase does not bring them back.
Things picked with Pro's three a month in the shop, things got with decorating tickets, and things Plus brings are kept on your device (and in its backup). The store's Restore purchase does not bring them back.
Refunds follow the App Store's or Google Play's own process and rules.

Crayon Plants Plus (an auto-renewing subscription)

Plus has a monthly plan and a yearly plan (one or the other). It renews automatically at the same price unless cancelled at least 24 hours before the period ends. Payment is charged to your Apple ID (your Google account on Google Play) when you confirm, and again at each renewal.
Free trial: the monthly plan may come with its first month free for those who have never had it (once per store account; shown where you buy). Unless you cancel at least 24 hours before the free month ends, the monthly price is charged automatically when it ends. If you cancel during the free month, you pay nothing. During the free month, Pro's 20 more plants from photos are not available; they come with your first payment.
Cancelling: you can cancel at any time at your store: on the App Store in Settings › your name › Subscriptions, on Google Play in the Play Store under Payments & subscriptions › Subscriptions. Manage subscription on the app's Plus screen opens it too. Deleting the app does not cancel it. After you cancel, Plus lasts until the end of the period you have paid for; there is no refund for the rest of a period, unless your store's rules give one.
Switching plans: the monthly and the yearly plan replace each other, so you never pay for both. Your store decides the day it changes over.
What you have while you are a member: Pro's features (picking 3 things from the shop each month comes with Pro bought once), 10 questions about the leaves each month (those not used do not carry over), and for each month from the day you joined, 3 decorating tickets and a seasonal item. The tickets and things that came stay yours after Plus ends. When Plus ends, Pro's features and the monthly questions end with it (if you bought Pro, Pro stays yours).
Plus works with the store account you joined with. It does not move between iPhone and Android.
We may change what Plus includes. We will tell you in the app at least 30 days before any significant change that is worse for you, and ask for your consent where the store's rules require it. Price increases are announced as the stores require.

The free version shows banner ads, limited to ads suitable for all ages. Pro and Plus have no ads.

What you must not do

Tamper with or reverse-engineer the app or our server, use it with cheating software, or exploit flaws to get things, tickets or questions.
Infringe other people's rights or privacy with your photos or notes, or harass others through the friends or family-sharing features.
Misuse purchases or refunds.
Break the law or public order.

If we find any of this, we may stop your use of the online features (friends, plants from photos, questions about the leaves, sharing with family).

Changes to the app, and ending it

The app may change as we improve it. If we stop offering the app or its online features, we will say so in the app or on this site at least 30 days before.

No guarantees

We do not guarantee that the app always works without interruption or error, works on every device, always delivers its reminders, that the AI's answers and drawings are right, or that your plants thrive. Data may be lost if your device breaks, is lost or is reset, with updates to the system or the app, or through connection problems.

Limits of our liability

Except where caused by our intent or gross negligence, we are not liable for loss or damage arising from your use of the app. Where we are liable, our liability is limited to what you actually paid for the app in the 12 months before the event that caused it. Where the law of your country (such as consumer protection law) does not allow these limits, that law applies.

Changes to these terms

We may change these terms as the law or the app changes. We will post the new terms and the date they take effect on this page and in the app beforehand, and give at least 30 days' notice of any significant change that is worse for you.

Governing law and courts

These terms are governed by the laws of Japan. Unless the law says otherwise, any dispute about these terms or the app goes to the Tokyo District Court as the court of first instance with exclusive jurisdiction.
