Premium Features
Premium unlocks unlimited sends and downloads, larger uploads in more file types, bigger article digests, and priority processing. About $2 adds 30 days of access.
What's included in Premium
Unlimited sends and downloads
- Free: 2 sends to your Kindle and 2 downloads a day: two separate counters, so a download never eats into your sends (and uploading a file counts as a send)
- Premium: unlimited sends and unlimited downloads, every day
More file types, larger uploads
- Free: PDF only, up to 3 MB per file
- Premium: up to 10 MB per file, in PDF, EPUB, DOCX or MOBI
Bigger article digests
- Free: a digest holds up to 2 articles
- Premium: a digest holds up to 10 articles, scheduled up to 3 days ahead
Priority processing queue
- Free: standard processing
- Premium: sends are processed first
Email support from the developer
Questions go to tokindle@icloud.com and are answered by the developer directly, free and premium alike. There is one inbox and one person behind it, so there is no separate support tier to buy.
How Premium works
Premium is not a subscription. It is a one-time payment that adds time to your account:
- One purchase = 30 days of premium access
- Buy again any time to stack more days
- Nothing auto-renews and nothing is billed without you buying again
Pricing is in your local currency, about $2 USD, through Buy Me a Coffee.
How to upgrade
Step 1: Visit the pricing page
Go to the pricing page and click "Get Premium".
Step 2: Use your toKindle email
When you buy through Buy Me a Coffee, use the same email address you registered with toKindle. This is how premium is linked to your account automatically.
Step 3: Instant activation
Premium activates automatically, usually within minutes. No manual step needed.
Step 4: Start using Premium
Unlimited sends and downloads, larger uploads in more file types, and 10-article digests are available right away.
Frequently asked questions
What email should I use when upgrading?
The same email address you registered with toKindle. This is how premium is linked to your account.
Is this a subscription?
No. Each purchase is a one-time payment that adds 30 days. Nothing renews on its own.
Can I stack multiple purchases?
Yes. Buy again to add more days; your premium time accumulates and does not expire while it lasts.
What happens when premium expires?
You get a reminder email 3 days before it expires. After that you return to the free tier (2 sends and 2 downloads a day). Buy again any time to reactivate.
Can I get a refund?
Refunds are not offered, since payment processing fees are non-refundable for a solo developer. Try the free tier first to see if toKindle fits your needs before upgrading.
What payment methods are accepted?
Buy Me a Coffee accepts credit and debit cards, PayPal, Apple Pay, Google Pay and other local payment methods depending on your region.
Will my premium work on all platforms?
Yes. Premium is tied to your account, not your device: Android app, Chrome extension and Firefox extension all pick it up.
