What we collect
Account information. Your email address, used to sign in and to contact you about the service. We don't require a password if you use magic-link sign-in. We don't ask for your name, phone number, or social-account credentials.
Plant information. The plants, seeds, and observations you add to your garden, along with any notes, nicknames, or photos you attach.
Photos you submit. Photos you take or upload for plant identification, disease/pest checks, or social posts.
Location. If you grant location access, we use it to generate weather-adjusted watering schedules. You can decline location access and enter a hardiness zone or ZIP code manually instead. We do not track your real-time location.
Device information. Standard technical data (device type, operating system, app version, language preference) needed to deliver the service and diagnose issues.
Subscription status. Whether you have an active subscription, trial dates, and credit balance.
We do not collect contacts, calendar data, microphone access, or web browsing history.
How we use what we collect
To deliver the service: identify plants, generate watering schedules, fire reminders, save your garden across devices.
To communicate with you about your account or important service changes.
To improve the product based on aggregate usage patterns. We don't link these patterns to your identity in ways that would let us or anyone else single you out.
To meet legal obligations and respond to lawful requests.
We do not use your information for advertising, retargeting, or behavioral profiling. We do not run analytics that share your data with advertising networks.
Who we share information with
We share information only with services that help us run Ezina, and only the information they need to do their job.
Plant.id receives photos you submit for plant identification and health assessment. It returns species matches, similar reference images, and disease findings. Plant.id receives image bytes and an optional location hint. It does not receive your name, email, account ID, or any other identifying field.
PlantNet receives photos you submit for identification. It returns species matches drawn from citizen-science contributions. PlantNet receives the same scope as Plant.id: image bytes and optional location hint.
Google Cloud Vision SafeSearch receives photos you submit to social posts for content moderation. It returns a content-classification result. This functionality is required for social applications where photo sharing is allowed. We are aiming for a locally hosted solution post launch to provide you greater privacy and remove Google’s interaction with our products where possible.
Microsoft PhotoDNA receives a cryptographic hash of photos you submit to social posts. PhotoDNA checks the hash against a database of known illegal content (such as child sexual abuse material). If a match occurs, we report to the National Center for Missing & Exploited Children (NCMEC) as required by US law.
Supabase hosts our database, authentication, and storage infrastructure on our behalf. Supabase is bound by a data processing agreement and acts only on our instructions.
Apple and Google receive subscription transaction information through their respective in-app purchase systems.
Wikimedia Commons is not a recipient of your data. We retrieve plant reference photos from Wikimedia on our side and display them alongside identification results. The flow is one-way: we read from Wikimedia, we send nothing to it.
We do not share data with advertisers, data brokers, analytics resellers, or any company whose business is targeting users.
We may disclose information when required by law (subpoena, court order, regulatory request) or to protect rights, safety, or property. When practical and lawful, we will notify you before disclosure.
Data retention
Account and plant data: retained while your account is active and for 30 days after deletion to allow recovery in case of accidental deletion.
Photos: retained while you keep them in your garden. Deleted photos are removed from our active systems within 30 days, and from backups within 90 days.
Subscription records: retained for 7 years as required by tax and accounting regulations.
Aggregated, non-identifying analytics: retained indefinitely.
Your rights
You can:
Access your data through the app (your garden, observations, settings).
Export your data in machine-readable format from Settings.
Delete your account at any time. Deletion is permanent after 30 days.
Correct any inaccurate information through Settings or by emailing support@get-ezina.com.
If you're in the EU, UK, or California, you have additional rights under GDPR, UK GDPR, and CCPA respectively, including the right to object to processing and the right to lodge a complaint with your local data protection authority.
To exercise any right, email support@get-ezina.com. We respond within 30 days.
Children's privacy
Ezina is not directed at children under 13. We do not knowingly collect information from children under 13. If you believe a child has provided information to us, contact support@get-ezina.com and we will remove it.
For users aged 13 to 17, we recommend parental consent.
International users
Ezina is operated from the United States. If you use Ezina from outside the US, your information is transferred to and processed in the US. By using Ezina, you consent to this transfer.
For EU users, we rely on Standard Contractual Clauses or equivalent safeguards for cross-border transfers where required.
Security
We use industry-standard measures to protect your information, including encrypted connections (TLS), encrypted storage, and access controls. No system is perfectly secure, but we take responsibility for protecting what you trust us with.
If we ever experience a data breach affecting your information, we will notify you as required by law and within a reasonable time of discovery.
Changes to this policy
We may update this policy as Ezina evolves. When we do, we'll update the effective date at the top. For material changes, we will notify you through the app or by email before the change takes effect.

Community Guidelines
Effective date: [TO BE SET ON PUBLICATION]
Last updated: [TO BE SET ON PUBLICATION]
Ezina is a place to share what you're growing, ask questions, and learn from other people who care about plants. These guidelines describe what's expected when you post in our social features and how we handle content that crosses the line.
The goal is a calm, supportive space where people learn about nature together.
What's welcome
Photos of your plants or garden
Questions about identification, care, or troubleshooting
Sharing what's worked or hasn't worked for you
Helpful responses to other people
Constructive feedback on plant care decisions
Honest reviews of products you've tried
What's not welcome
The following content will be removed and may result in account suspension or termination.
Illegal content
Child sexual abuse material (CSAM). We use Microsoft PhotoDNA to detect known CSAM in uploaded photos and report apparent matches to the National Center for Missing & Exploited Children (NCMEC) as required by US law.
Other illegal content under US federal or state law.
Illegal content
Harassment, threats, or targeted abuse
Hate speech or content that demeans people based on race, ethnicity, national origin, religion, gender, sexual orientation, disability, or any protected characteristic
Content that encourages or instructs self-harm or violence against others
Sharing someone else's personal information without permission (doxing)
Sexual content
Sexually explicit imagery or content
Solicitation of sexual content from other users
Deception and abuse
Impersonating another person or Ezina itself
Spam or repetitive posting designed to drive traffic elsewhere
Misleading commercial promotion presented as personal recommendation
Scams or attempts to defraud other users
Off-topic content
Content unrelated to plants, gardening, or growing
Bulk political or ideological campaigning
How we moderate
Automated tools check uploaded photos for prohibited content before they appear publicly. Google Cloud Vision SafeSearch handles general content classification. Microsoft PhotoDNA handles CSAM detection through cryptographic hash matching.
Users can report any post, comment, or profile they believe violates these guidelines. Reports route to a human review queue. We aim to act on reports within 48 hours.
When we find content that violates these guidelines, we may:
Remove the content
Issue a warning to the user
Restrict the user's posting ability temporarily
Suspend or terminate the account
Report to law enforcement if required by law
Decisions depend on the severity of the violation and the user's history.
How to report
If you see content that violates these guidelines, tap the Report option on the post, comment, or profile. Tell us what's wrong in a short note. Reports go to our review queue.
You can also email support@get-ezina.com with the link to the content and what you think the problem is.
Changes to these guidelines
We may update these guidelines as the community grows. When we do, we'll update the effective date at the top. We'll notify you through the app or by email if changes are material.

Terms of Service
Effective date: [TO BE SET ON PUBLICATION]
Last updated: [TO BE SET ON PUBLICATION]
These terms describe your relationship with Ezina LLC ("Ezina," "we," or "us") when you use the Ezina app and related services. Please read them. By using Ezina, you agree to them.
Eligibility
You must be at least 13 years old to use Ezina. If you are under 18, you should have a parent or guardian's permission.
You agree to provide accurate information when creating an account and to keep it accurate.
Your account
You're responsible for what happens through your account, including keeping your sign-in method secure. If you think someone else has accessed your account, tell us at support@get-ezina.com.
We use magic-link sign-in by default. We send a one-time link to your email instead of asking you to set a password. Keep your email account secure.
The service
Ezina helps you identify, track, and care for plants. It includes:
Plant/Disease/Pest identification using photos
Watering recommendations based on numerous factors including your zone, your plants, soil type, and your local weather
Seed germination tracking
Indoor and outdoor plant care guidance
A social layer for sharing your garden with other users
Care reminders via push notification
We're a small team and the service is offered as-is. We work to keep it running and accurate, but we don't guarantee it will be available without interruption or that every plant claim will be perfect. Plants are living things, and care is judgment as much as science. Use Ezina as a guide, not a replacement for your own observation.
What you can post (User Content)
When you add a plant, photo, comment, or other content to Ezina, you keep ownership of it. You may grant us a non-exclusive, worldwide, royalty-free license to store, display, and use your photos to help market and share the service. This feature is opt in on an account level. You may choose to end this licensing when you delete the content or your account.
You agree that your content does not violate our Community Guidelines, infringe on anyone's rights, or break any law. You're responsible for what you post.
We use automated moderation tools, including Google Cloud Vision SafeSearch for general content and Microsoft PhotoDNA for detecting known child sexual abuse material. We also rely on user reports. Content that violates our Community Guidelines or the law may be removed. Accounts that repeatedly violate may be suspended or terminated.
We are legally required to report apparent child sexual abuse material to the National Center for Missing & Exploited Children (NCMEC) and to preserve related records.
Acceptable use
Don't use Ezina to:
Post content that violates our Community Guidelines
Impersonate someone else
Advertise goods or services.
Scrape, reverse-engineer, or attempt to interfere with the service
Use the service to harass, harm, or surveil others
Resell or commercialize the service without our permission
Subscription, billing, and cancellation
Ezina offers a 14-day free trial. We do not require a payment method to start the trial.
After the trial, continued use requires a subscription:
$6 per month (monthly)
$60 per year (annual)
Subscriptions purchased through the Apple App Store or Google Play are billed through those platforms and governed by their terms. Subscriptions purchased directly through Ezina (when available) are billed through Stripe.
You can cancel any time through the same channel where you purchased. Cancellation takes effect at the end of your current billing period. We do not pro-rate partial periods.
Refunds
If you're not satisfied with Ezina, email support@get-ezina.com and we'll process a refund. No questions required. For Apple or Google subscriptions, you may need to request the refund through the platform that processed the payment. We'll help where we can.
Our intellectual property
Ezina, including the app, its design, brand, illustrations, and underlying code, is owned by us. You can use it for personal, non-commercial purposes as long as you comply with these terms. You don't get any ownership or rights to redistribute it.
Disclaimers
Ezina is provided as-is, without warranties of any kind. We don't guarantee that the service will be uninterrupted, error-free, secure, or that plant care recommendations will be correct for your specific conditions.
To the maximum extent permitted by law, we disclaim all implied warranties, including warranties of merchantability, fitness for a particular purpose, and non-infringement.
Limitation of liability
To the maximum extent permitted by law, Ezina LLC is not liable for indirect, incidental, special, consequential, or punitive damages, or for any loss of profits, revenue, data, or use, even if we've been advised of the possibility of such damages.
Our total liability for any claim arising out of or related to the service will not exceed the greater of $50 or the amount you paid us in the 12 months before the claim.
Termination
You can stop using Ezina any time by deleting your account through Settings or by emailing support@get-ezina.com.
We can suspend or terminate your account if you violate these terms, the Community Guidelines, or the law. We'll usually give you notice before doing so, except where doing so would expose us or others to harm or legal risk.
Sections of these terms that should reasonably survive termination (including those about content licenses, intellectual property, disclaimers, limitation of liability, and dispute resolution) will continue to apply after termination.
Changes to these guidelines
We may update these terms as Ezina evolves. When we make changes, we'll update the effective date at the top. For material changes, we'll notify you through the app or by email before the change takes effect.
If you keep using Ezina after the changes take effect, you accept the updated terms.
